Comment and I will:
1. Tell you why I added you to my friends list and/or why I keep you there.
2. Associate you with something. A song, a color, a work of art, a character in a play, a piece of fruit. SOMETHING.
3. Tell you something I like about you.
4. Tell you a memory I have of you/us.
5. Associate you with a character from a book or a film.
6. Ask something I've always wanted to know about you. (Or else I'll just ask a random question. I reserve that right.)
7. Tell you my favorite user pic of yours.
8. In return, you must spread this disease in your LJ.
