One of my friends asked me this interesting question,"Am I your friend?"
I was thinking for a while, and "What do you think?" I said.
She seemed to be confused then.

I said "It's such a stupid question you've got...You know, true friends don't need to think about that,
Because they know that they are." (^-^)

Yeah, Whatever. Haha... =P

You know me, I won't talk to people who I dislike.
I don't call up a person who I hate, to go out for a dinner.
I wouldn't have a sleep-over who I think he/she's not my friend.

Don't worry about it.
No need to think about it.
We are friends, always.
