Girl or Boy?

Apparently, they've been talking about the difference between boys and girls at Carter's school lately.  How do I know, you ask?  Well, lately Carter's been saying things to me like, "Let's play basketball, girl" or "Come on, girl, let's play."  He means no disrespect, and I find it kind of humorous...but here's the best yet...

On the way to meet my parents for lunch today, we passed BGA.  Here's the dialogue that ensued:

Carter:  Mommy's school.  You teach girls there. 

Me: Yes, but I teach boys too.  What's mommy?

Carter:  A girl.

Me:  What's daddy?

Carter: He's a boy, too.

Me (attempting to see if he truly gets the concept):  What's Don-Don?

Carter: Crazy! 

We love you, Don-Don! :)
