13. My daughter is a polar bear and I am a lizard

Today it was 39 degrees outside. Yes it was sunny and that makes a little bit of a difference but it was still really cold to me. However my daughter Greta stood at the back window saying "back, back, back, back," (meaning backyard) over and over again. Finally I gave in and bundled up. The cold did not even phase her. Are babies born with different skin than adults. She would stick her hand in the icy snow and not even flinch. Her nose and hands were really cold but every time I tried to take her back in she would do the back arch temper tantrum. I love that she enjoys playing outside and maybe she will keep me from hibernating all winter long. After school my son took her outside to play so I could thaw out. When I peaked out back he had his shoes off and Greta had taken her coat off. How could this be? Oh to be young again and have no temperature gage.
