What do you think Gavin is thinking as he smiles (smirks) for this picture a couple of days ago?
"Mom....I can't believe you had a camera with you"
"You want me to sit here and smile while that giant needle is on its way to me??"
"Why couldn't they give me a more manly bib/napkin??"
"Maybe I can ask the dentist to give the Nitro to my mother."
