"Robot Leg"

I took the girls with me on a mad dash to Walmart this morning for oreos, twizzlers, chips and pop...you know, the essentials for camping! Well, there was a man with a prothsetic leg walking in front of us, and it was just a metal pole kind. I was sort of bracing myself for a comment from the kids...and Avery said, "Hey mom, that robot leg is freaking me out!" I hushed her and quietly said, 'sweetie, something cut his leg off and now with that he's happy he can walk again. if something happened to your leg, wouldn't you want a robot leg to help you walk?" She stinking puckered her face thoughtfully and asked, "welllllllllll.....do you think it comes in pink?"
