Folding preflop

22 UTG, I limp, few limpers, then the guy who got check raised on the river and folded raises to $25. I think he's on tilt and unlikely to have anything to pay me off with...so I fold. Flop: 42J. Just as I'm swearing to myself the two guys both go all-in. The callers got a set, I know, and results wise that was a fantastic fold by me. Caller shows JJ, tilto shows KK. I totally misread him but boy am I glad that I did.

Also, I don't know what I was doing not calling for set value enough in that session. I guess I hate money.
