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. If I do this for you, you must (please) post this on your journal so you can do the same for other people
