Say What?

I'm away on a business trip, but this nugget of goodness happened before I left.  We were in the kitchen, the whole family.  I was working on dinner, Dan was loading the dishwasher, all of the girls were talking at once.  I wasn't really paying attention until I heard, in the cutest, tiniest girl voice:  "And THAT really pissed me off."

Ahh, it was the Moo.  And she used the language in the correct way.  I was kinda proud.  And I kid you not, my first thought was "oh, shit."  I KNOW, very helpful, right.

Me, quizzically, "Did you just say that something pissed you off?"

Three, in a sing-songy voice: "Pissed off, pissed off pissed off pissed off pissed off, piiiiiiiiiiiisssssssed off off off."

Moo:  "Yeah."

Silence.  Dan and I pause and look at one another.

Me: "Well that isn't a very nice way to put it.  I know that I say that phrase all the time, Moo, but it is one of those things I shouldn't say.  I should choose better words.  And saying that you are pissed off is one of those unfair things that adults can do but kids shouldn't.  It's not nice manners."

Moo:  "Ok."

Dan: "This one was all you...."

Me:  "I'm aware. But I'm sure your turn is coming soon."
