Cat that ate the canary

I took the girls to get their passport photos taken.  They were both really, really excited about the idea of getting a passport and traveling the world.  But, Gwen didn't want to show her braces and Caitlin was trying to be a bit serious, I think.  So, both of them smiled with their mouths shut.  Huge smiles but not a glimpse of teeth!  Imagine a cat that has been salivating over her owner's precious pet canary for months.  Imagine the cat has just caught the bird and still has it in her mouth but doesn't want the owner to see the bird.  This is exactly what their passport photos look like.
