While working as a mall Santa, I had many children ask for electric trains. "If you get a train," I would tell each one, "you know your dad is going to want to play with it too. Is that okay?"
The usual answer was a quick yes, but after I asked one boy this question, he became very quiet. Trying to move the conversation along, I asked what else he would like Santa to bring him. He promptly replied, "Another train."
