I should also mention that I don't think I really gave off a tell.

What happened was, during the next hand he said "I want my cards back. I changed my mind. I call. You didn't have it". He was really regretting laying it down.

I said, "Nah, I had top set. Good fold. You shouldn't have shown your cards with action to follow though".

At this point, his demeanor totally changed. He became really happy, hinted he spotted a tell, and also would not admit that showing his cards there was bad. He said he could still have pushed all-in.

I tried to explain that showing his cards would make my decision to call or fold really easy. He wasn't having it though, and no one could convince him he should not have opened his cards unless he was definitely folding.

Also, people I had been at the table with the whole time had thought he made a terrible fold.
