Because it's easy and I can complete it in a manner of minutes:

1. I'll respond with something random I like about you.
2. I'll tell you what song/movie reminds me of you.
3. I'll name something we should do together.
4. I'll say something that only makes sense to you and me (or just me).
5. I'll tell you my first/clearest memory of you.
6. I'll leave you a quote that is somehow appropriate to you.
7. I'll ask you something that I've always wondered about you.
8. Tell you to pass it about, but you know what? If you want to do it awesome, if you don't, that's fine too.
