When I picked Tink up at my Mom's the other evening I was told that Tink had scolded my mom (Mamaw) that day.
Mamaw had apparently told one of my nephews to shut up. (I don't allow the words shut up at my house.)
Tink told Mamaw "My mother and I have had this discussion. We don't say shut up. That's a bad word. We say shhh or please be quiet. So don't say that anymore Mamaw. Okay?"
Mamaw agreed that it wasn't very nice to say and asked Tink to remind her if she heard her say it again.
