The cold is the best.

One day in the garage, little Tom took a bath with his mother. Tom asked his mother curiously, "What is this?" (Pointing to the bottom of mother) Mother replied, "This is the garage". Little Tom in the world said, "Then what am I?" Mother replied, "It's a car." Little Tom said; "Then can my car drive to your garage?" W mother said, "No, your father's big truck will come in at night." In the evening, little Tom had a nightmare and ran into his parents' room. When he saw his parents doing something, he shouted in surprise, "Dad, your big truck has already entered the garage. Why are the two wheels still outside the garage?"
