Played for the first time in three weeks. Offline due to a number of factors: computer virus, baby (cutie :-D !), Christmas plans, etc.

Guess what happened?

micro cash game, on THE FIRST HAND, My full house ( 10s full jacks, My hole cards were 10 10) got busted by FOUR of a kind - jacks. Opponent's hole cards were J4

Why oh why?!
