Leave a comment and I'll...
1) Tell you why I friended you
2) Associate you with something - fandom, a song, a colour, a photo, et cetera
3) Tell you something I like about you
4) Tell you a memory I have of you
5) Ask something I've always wanted to know about you
6) In return, you must post this in your journal. (okay, you don't have to if you don't want to)
