What is love anyway?

Is love just that funny feeling you get between your legs?
Is love thinking about someone everyday and every minute?
Missing them even when they have just left?
Is love thinking that you don't want to live without them?
Is love doing anything just to be with them?
Is love really patient and kind?

Because so far, I don't think love has been kind at all.

Does love wait? How long does love wait? Should love wait? When does love change from love to just being someone's doormat?

All I know is what someone once told me.
Love should make you smile. It does makes me smile. So I guess love will wait, until the smiles are replaced by tears.
