Chatting and too much info. (LC)

While playing a little while ago and not in the current hand, a player got upset about losing a hand. Here was the board:

TH 6C 4C 3C, 7D.

The winner had AC 7C for the nut flush. The loser mucked his hand.

Of course, with PAHUD, I knew the loser had TS 4H (2 pair).

Another player replied with "Thats what you get for playing 10-4".

I immediately typed "I was thinking the same thing".

I then realized that this table full of fish was going to wonder how we both knew immediately what was folded. To my surprise, nobody even commented on it. The original poster and I soon left the table. I guarantee that there was nobody else in the hand who could even spell PAHUD, let alone knew what it is.

Anyone ever type something in the box without thinking of the consequences? I usually stay out of the chat box, and in fact pick up a lot of information when others say something after a hand. For some reason, I felt compelled to reply this time though.

Thoughts?
