When my nephew was about 4, a friend of our family was in town visiting. The friend had a white beard and my Dad jokingly told my nephew that the visitor was Santa (this was in July). Two days later, my nephew was playing in his backyard when my Dad and the friend drove into the driveway. Nephew RAN into the house, changed his shirt, washed his face and brushed his teeth. His mother asked him what he was doing and he replied "Santa's here to see if I'm being good and I AM being good!"
