1. The first character I first fell in love with: Sirius Black, quelle surprise. He's loyal to a fault, rebellious, emotional, defiant, brooding, passionate, confident, and oh so sexy! How could you not fall in love? Of course, I will always love Harry. But in a way, it's kind of comparing apples and oranges.
2. The character I never expected to love as much as I do now: Right now, I'm saying Luna. I love her matter-of-factness, her fearless quirkiness, and her strong sense of self. When I first met her, I thought she was cool and interesting; it was only a bit later that I realized how truly awesome she is. But I have a feeling that once I complete my rereads of Order of the Phoenix and Half-Blood Prince, Ginny may outrank her in this respect. I never disliked Ginny, but she's definitely growing and growing on me. I think once my rereads are done, I will truly adore her.
3. The character everyone else loves that I don't: I don't know how many people love this character, actually, but I'm gonna go with Tonks. I don't feel that she's very well developed in canon, and I just don't find her very interesting. She's nice, but blandly so. Maybe she's not flawed enough for me. Again, I do need to reread the fifth and sixth books, so maybe my opinion will change, but for now I declare her too two dimensional for my tastes. And the Metamorphagus thing is just meh for me.
4. The character I love that everyone else hates: I can't really think of anyone for this. I adore Hermione, but so do a lot of people. The same goes for Ron. Lucius? A lot of people find him intriguing, and I'm not sure I actually love him. It's hard to separate canon!Lucius from JasonIsaacs!Lucius. Snape? Same problem with canon!Snape vs. AlanRickman!Snape, and moreover, a lot of people love him as well. The same could be said for Draco. Maybe the closest I can get to answering this question would be to say Peter Pettigrew...except that I don't love him. But the reason I say him as a possibility is that I think MaraudersEra!Peter must have had some really redeeming qualities for the other guys to give him the time of day. What we saw in the Pensieve cannot be all there was to Peter. If that's the case, Sirius would have given him the boot long before they made it to their O.W.L.s. So, I think there must have been something to love about Peter. This is something I want to develop in my fan fic "Yellow", actually. Unfortunately, so far Peter has somehow managed not to be in my Marauders-era flashback scenes so far (through Chapter 3, which I'm still working on). He made a cameo in one, but then decided to leave the room, and there was nothing I could do about it! But I do want to portray a good side of Peter, so we can understand why James, Sirius, and Remus were such good friends with him, and why Sirius even says he would have died for Peter in Prisoner of Azkaban.
5. The character I used to love but don't any longer: Another tough one. Aragog? Just kidding. Molly really pissed me off in Order of the Phoenix (no one hits my Sirius below the belt!), so maybe I'll say her. But once again, I need to reread the last two books to say that definitively.
6. The character I would shag anytime: Sirius Black! That's an easy one!
7. The character I'd want to be like: Well, I'm very much like Hermione already. But who I'd want to be like? I think I'll go with Harry, our hero, here. I consider myself a loyal friend, but he's got me licked. I mean, he doesn't even hesitate for one second when it comes to risking his life to save the ones he loves. I think I'd ultimately make the same choices he does, but I also think I would hesitate.
8. The character I'd slap: Umbridge. Not only is she completely evil in a sickly sweet sort of way, but she reminds of this truly horrid English teacher I had in the 9th grade.
9. A pairing that I love: I have three answers for this one. My fanon answer is Remus/Sirius. There's something very sweet (and very hot!) about this pair. The two are perfect foils for one another, and there's so much history and so much hurt between them that the angst and drama factor rises to delicious levels. My second answer does exist in fanon, but in a very small capacity, and it's a ship that I actually made up myself without seeing it in fanon first. It was only when I Googled it that I realized I wasn't the first to think of it. Of course, I had figured as much; every possible pairing out there has probably been written, from Crookshanks/Mrs. Norris and Grawp/Firenze to Fat Lady/Bloody Baron. (Oooh, now there's an idea for a good crack!fic challenge: Write a crack!fic featuring the most unlikely pairing you can think of, and not just something that people joke about a lot, like Dobby/Giant Squid.) Ready? It's Sirius/Rosmerta. For some reason, I can see Sirius going for an older woman like her, just because it's dangerous, and possibly forbidden. (Well, we don't know how much older she is, but she has to have been at least several years older if she was tending bar when the Marauders were in school.) Plus, except for possibly her blood lineage, she is probably everything the Black clan would hate: a woman of a lower class, employed in a service industry. In fact, she is the only woman in canon I can see with Sirius. This pairing is a new discovery for me, and it was stimulated by a little flirtation that wrote itself into Chapter 3 of "Yellow". (Just to be clear, "Yellow" doesn't ship Sirius and Rosmerta, because that relationship is likely not canon, or else Madam Rosmerta would have been even more horrified during the scene where Harry overhears Fudge, Hagrid, McGonagall, and Rosmerta in The Three Broomsticks. But I could see Sirius flirting with Madam Rosmerta, so that's what I included--not an actual relationship.) And my third answer, which is the canon answer, is just OBHWF. Just because it's canon. And it works. And it's just right.
10. A pairing that I despise: Oh boy. I know some people are not going to like this one, but I really do not like Lupin/Tonks. This is mainly because I do not like Tonks and because I really just don't see it. Once again, a reread of the fifth and sixth books could change this, but...I dunno, I don't think so. Even though I never saw Remus/Sirius as canon, I have trouble seeing anyone else with Remus but Sirius. And yes yes, I know, Remus is not gay and Sirius is dead...and I do want Remus to be happy. But Tonks is just too two dimensional for me to enjoy this ship. Hmm, and maybe I don't want Remus to be happy. Maybe I like the angst. I don't know. I just don't see this ship. And, of course, Harry/Hermione was always a nonentity for me. Leaving aside the shipping wars, they really are way too siblinglike for me to see any trace of a ship. Further, Harry clearly states in Goblet of Fire that his time spent with Hermione when he and Ron weren't talking wasn't particularly fun. There's just no romantic chemistry there. Period. As for fanon ships, there are way too many squicky ships to name. Particularly insidious ones, though, are anything involving incest [e.g., Lucius/Draco, Twincest (Fred/George)], Snape/most people (especially Lily, Remus, Sirius, James, Harry, Hermione, and Draco), and Harry/Ron (best friends typically do not shag each other!).
