Phone etiquette

Brannon loves talking on the phone. He knows all the numbers in my speed dial and who they belong to. He usually talks on the phone on the way home from school most days (unless he can't get anyone and then he will sadly talk to me). Yesterday he was talking to his MeMe and I was reminding him of a couple of things he had done that day that he should share with her. He put his hand over the phone and in the sweetest voice said "Mommy, I'm talking on the phone and you're not supposed to talk while I'm on the phone." Then he went back on with his conversation. I guess he was listening when I gave him that lecture the day before. I guess I'll have to start practicing what I preach!
