This one brought to you by Caleb...
"Mommy, when we grow up, Sarah and I are going to be polices. We are going to work at the same police station. We can give each other kisses. We can share a police car. We can have a police dog."
Right now, those kisses are so sweet. Brother to sister. One day, he'll be repulsed by the idea of even hugging his sister, I'm sure.
I love that boy!
