Little voices

I sit at my computer while the boys watch a movie (Audrey is at book club). They are on the couch. I hear little voices drifting:

Matthew to Austin: You're stinky
Austin: I not stinky
Matthew: You're stinky
Austin (giggling): I not stinky, G'ma is stinky.

I glance in their direction. They are not paying any attention to me. Suddenly four little blue eyes pop over the back of the couch and look at me. They smile and turn back around.

Matthew: G'ma not stinky. You're stinky.

Thank you, Matthew!
