1) Tell you why I friended you.
Ummm... No specific reason. You're someone I knew before I was on LJ, so when I joined and saw you there it made sense to add you.2) Associate you with a song/film.
See my answers to this question, above. But you're the only person who goes on about anime on my friends page, so that would condition the choice of film if I knew anything about the field.3) Tell a random fact about you.
It would probably be something to do with your endocrine system, or your PPL.4) Tell a first memory about you.
You've been around in ZZ9 for ever, certainly longer than me, so if I could remember anything it would probably be something ZZ9-related. But since I've known you easily twice as long as anyone else who commented here, it'll be too long ago for me to remember.5) Associate you with a character/pairing.
Again, if I knew anything about the field it would be some Japanese animated character ... but I don't.6) Ask something I've always wanted to know about you.
See my answers to previous correspondents -- were there something, I'd have asked already.7) Show you my favourite user pic of yours.
This one, the one you're using as a default at the time of your comment, I quite like.
