The thing with online poker is that you have NO idea whatsoever what the other players' situations are. Imagine if you will that you're a wealthy man blowing your money at online poker tables, but in the middle of your game, your wife starts nagging you and your kids are screaming and crying, and the phone is ringing and no one will answer it. The guy next to you goes all in preflop and you have 2 suited cards, 1 high 1 rag, wtf why not go all in too? Getting rivered and beaten by bad beats is as much a part of poker as the cards themselves. Sorry you lost that but all you can do is shake it off and wish for better luck to you next time.
