These things change?

My precious Boog is so funny...

Boog: "Mommy? What are you looking at pictures of?"

Mommy: "Me when I was in school."

Boog: "Oh, who was your mommy when you were a kid?"

Mommy: "Gee Gee"

Boog: "Still? When you was a kid she was your mom?"

Mommy: "Yep"

Boog: "Oh. Who was Daddy's mom when he was a kid?"

Mommy: "Grandma"

Boog: "Oh"

Some things just never change...
