Identity Crisis

A dad is talking to his son at church and trying to help him get the courage to introduce himself

Dad: Son, don't be afraid.  Say, "Hi, I'm Aaron.  What is your name?"

Son: <looks at me> What is your name?

Me: Erin.

Son: No, it's not!  

Me: Yes, it is.  What is your name?

Son: Aaron.  What is your name?

Me: Erin.  

Son: No, it's not!

<He stares at me incredulously> 

Me: Well, what do you think my name is?

Son: Melissa.
