I think its obvious he was mad because he was fighting it out for 2nd. when you pushed him out of the hand, he was upset because his hand was no longer live and he couldnt try to eliminate the short stack with you. when he flopped a set, it just rubbed salt in the wound you just opened. while i can understand how someone in his position was upset, if i were in your position, i do exactly the same thing. and it was the correct move after all...not only did you bet him out of the hand, but that won it for you, set him off and you ended up winning a short time later. Why let some chump upset that you took his chance at winning away let you question your game. well done.
