Humanity Lesson

An older doctor was debriefing a new doctor who had done done a good job in the emergency room. He said "Did you notice the young man from housekeeping who came in to clean the room?" There was a complete blank look on the young doctor's face. "His name is Carlos. He's been here for three years. He does a fabullous job. His wifes name is Maria. They have four children. He lives in a rented house about three blocks from here." Then he named the four children and gave each child's age. "Next week I would like you to tell me something about Carlos that I don't already know."
