Little Funny

I was driving the girls today somewhere and charging my cellphone on the car charger. The girls spent quite a while discussing what this might be before they actually bothered to ask. When I told them that my cell phone was charging, Betsy said, "Oh that's just like changing the batteries." I said "Yes, Betsy, that's exactly right." She must have sensed that I was a bit surprised and pleased with her answer when she responded with, "Mom you are so very proud of me, aren't you?"
