So, how did that work for you, Katie?

I think I need to read this post more carefully.

Gracie came running upstairs to get Mary Beth. Mary Beth ran downstairs with Gracie and then came up to get Paddy. Hmmm...mom's suspicious.
Downstairs, we find Katie under the kitchen table with egg yolk all over her bottom.

She wanted to hatch the egg and have a chicken. So, she sat on it.

Of course.
