Retarded Laydown?

[Chino987]

Stupid loose 4/8 live game.

Few limpers, i raise AQo in MP, buttons calls, annoying old passive lady calls in BB, everyone calls.

Flop is AJx no suits, check to me I bet everyone cept for 1 limper calls.

Turn Q, check to me I bet, everyone calls.

River K, old lady bets, everyone folds I fold face up in total disgust.

Earlier this person check called my TPGK (QJs) with an underpair (88) turned a set and never bet/raised the whole way.

Retarded fold? I think my play might have been driven by ego (i.e. no way i'm paying this annoying passive old lady off god #@$% it) type thinking...you guys agree?
