Being PC..what's that?

I was showering my two girls this morning, when Sydney looked at me and said, "Mommy, you have a big butt."

Well, while I am feeling a little self conscience, Aubrey piped in, in efforts to rescue me. With that in mind, Aubrey tells her younger sister, "Sydney, mommy doesn't have a big butt, she has a small butt....like her boobies." Ouch...
