You are funny.
I get that a lot from people. Often, I don't know whether they meant "the last comic standing" funny or "what's wrong with you" kind of funny. Before this I thought that humor is one of my better attributes, and then I was introduced to the word sarcastic, and suddenly everything makes better sense.
Once, someone asked me if I was deliberately picking a fight with him because I disagree with everything he said. I denied then but now I'm incline to agree instead. Yes, I argue for the sake of argument. Nothing like a good conversation then agreeing to disagree.
