Pain in the Butt

Last night while jumping on the trampoline Abby got an attitude with Noah. Abby is very much the oldest sibling i.e. she's bossy. And last night she was laying it on thick with Noah. Telling him where to stand, how to bounce, when to bounce - the list goes on. Anyway I told her to stop, she didn't so I sent her upstairs. She was mad and Noah had to add his two cents as she was walking up the stairs.
"Mama, Abby is a pain in the butt"
Oh how hard it was not to laugh. He's just calling it like he sees it. I reminded him it's not nice to use those words and he said "ok, what about goodness gracious."
I told him that was better.
