This is what I heard from the back seat:
"Mom!! I can do my middle finger!!!"
Just as I was about to blame those shady big brothers, re: this post , or perhaps riding one too many times in the car while her father was driving (Just kidding - hehe)...
I realized that Lizzie was really just excited to be able to hold that middle finger up. She works with her little fingers a lot and this was just one more accomplishment, or...
maybe, she and those crafty brothers of hers have got me totally duped!! It would be easy to do. I mean just look at that face!
Naw, I think I will stick with accomplishment - that is what I am going to tell myself anyway!! Hehe!
