Please tell me what is then if you think you're so smart.
I wasn't picking a fight with you. I was stating that adding a question mark doesn't make it clear that you're implying sarcasm.
And btw, that's a good way of implying sarcasm. I can clearly see you're sarcastic when you say "if you think you're so smart". (Eventhough I never stated I'm smart, so I don't know from what you concluded that I think I'm smart).
