"Grandma Parts"

The following is an excerpt from a conversation the other day:

Adam: Mommy are you a boy or a girl?

Me:  I'm a girl.

Adam:  Why?

Michael:  (after a slight pause)  Mommy has girl parts.

Adam:  Is grandma a boy or a girl?

Michael: Grandma is a girl.

Adam: NO SHE ISN'T!

Michael/Me:  Yes she is. She has girl parts too.

Adam:  No she doesn't, she has grandma parts!
