Confession: I lost it and berated a fish the other night

[Mizzles]

Don't have the hand here, but this one put me over the edge. I'm already running bad for ~10 days when this happens..... I'm in early position w/ KK, I raise, mid position player 3-bets, button (~38/10) caps.

Flop is K 7 3r. I bet, MP folds, button calls
Turn J, I bet, button calls
River 8

I bet, button raises, I 3-bet, button caps and flips over 10,9o for the nut straight.

I blew up. I told him how much of a moron he was, how could he cap it cold preflop w/ 9,10o, etc. For what it's worth, I only berated him for about 2 sentences then I stopped. Not smart on my part.
