What is love?

What is love?
Is it a lie?
Is it a cause with no effect?
Is it a simple emotion?
Or is it a twisted way around friendship?
Is it a shortcut for physical affection?
Is it physical at all?
Is it a warm feeling?
Is it cold?
Is it uncomfortable?
Is it happy?
Is it indescribable?
Is it unconditional?
Is it me?
