People get STUPIDER every night

I played a little limit HE for the hell of it. In the course of 4 hands I got sucked out four times and lost ten bucks. The great hands that beat me are 2nd and 3rd pairs that either call 2-3 bets pre-flop with J2 or some idiot hand, flop the 3rd pair, turn either a set or nothing and then proceed to river a flush/quads/set on the river. I can not BELEIVE how bad people play and how much they get paid off.
