just when i thought i had it, i realized i had nothing in fact

One day, my friend asked me, "Do you have a best friend? Show me her picture on Facebook."

It took me a while before I could finally gave her an answer. I know that it is a very simple question. Say yes if I have one and say no if I don't. Anyway, I think further than that.

If we treat someone as a best friend, but we don't turn out to be the best friend of that person, is she still considered as your best friend? Yes? No? I don't even know.

To clear this up, I am not emo. Just a random thought that struck me while I listened to a song about Friends.
