It is all about the conversation

 Baby:  "You don't have a penis."
Queen:  "No I don't.  I am a girl."
Oldest:  "Yeah girls have a pahgina."

Oldest:  "Do you know what revenge is?"
Middle:  "No"
Oldest:  "Me niether."

I love listening to their conversations.  With Oldest in First Grade so much of their conversations have more to do with what things mean.  It is a wonderous time.
