Why I don't work-out

"Mommy? We were supposed to go to the Y[M]CA this morning!"
"Yeah, I know."
"Well, why didn't we go? Why didn't we go to the Y[M]CA?"
"Because...we just didn't."
"Why?"
"Oh, I don't know...we slept late."
"Nooooooo...I watched 'Little Einsteins'" (it comes on at 7).
"Oh for God's sake. We didn't go to the YMCA because mommy's a big, fat, lazy butt!"

SILENCE.

No one wants to argue with that. I feel hurt.
