live game with friends was this incorrect ?

[warchaser]

ok, livegame with friends, super low stakes but i dont care cuz we do this for fun really, and i like to win [img]/images/graemlins/smile.gif[/img]

so late in the eavening player 1 raises with ak and player 2 calls with 33
flop comes K58 or something and it goes bet-call,
turn comes a 3 and again it's bet-call,
river is another K so player 1 now has 3 kings and player 2 comments that he must have 3 kings now omg! what i doo.
Player 1 puts him all in and he goes in the tank, in this friendly livegame sometimes we show 1 player the hand that u can ask for help, he asked me and showed me 33, I say WTF u doin, DON"T slow up the game cuz this is stupid really, he still doesn't call.. So i repeat omfg! CALL already
he calls stands up and I state he has a full house, he looks weird and sits down and scoops the pot
of course player 1 wasn't too happy with what i said and thought player 2 was really gonna fold a set of 3's ( that made a full house on the river )
