I used to believe that Santa stayed in your chimney all year, and if you went outside and didnt see smoke, it meant he was fat, and if you did, he got skinnier. It made sense to me, considering we always went to picnics in the summer, and the fireplace was never lit in the summer, so I figured Santa ate a lot of left overs from the picnics. But, in the winter, he stopped eating so he could eat all the cookies, which was when the fireplace was always lit because it was cold.
