IDK.

I don't know you that much.

I don't know how to feel about you.

I don't know if I like you in that sense.

I do know that I enjoy endless IMing with you.

I do know that I enjoy poking you on Facebook.

I do know that I worry about you.

I do know that I want to get to know more about you.

I do know that your taste in music is ah-may-zing.

I do know that you make me smile.
