1. Tell you why I befriended you.
2. Associate you with something - fandom, a song, a colour, a photo, etc.
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. Tell you my favourite user pic of yours.
7. In return, you can post this on your LJ. (The original version said must, but I hate force-feed-me memes.)
