Tells

I have noticed lately a tell that almost always seems to be true in Internet Poker. It is a weird one. Perhaps I am overly sensitive. Maybe I would be a great B&M player picking up on unseen things in people's body language. The tell goes as follows. You are in a pot and the guy raises pre-flop. The board is small and he cannot wait to get his money into the pot. Sort of splashing the pot with his chips. You can feel the anxiety dripping off of him. He must convince you that he has a pair. The feeling I get when people do this is that they are so concerned I will not believe them that they need to force me to listen. I always call these people down to the river even if I have a small pair. If the A or K appears then I will stop, or maybe pay them off at the river just to confirm my suspicions. I do not think I have been off on this. Am I crazy? Do I have psychic powers? Am I psycho? Anyone else notice this?
