No doorbell

Mr. L was at my house watching a show on television. His older brother was at the computer a little ways away and I was in the kitchen for a few minutes. I thought I heard the doorbell ring but it wasn't loud enough to be the actual doorbell so I decided to go over to the room the boys were in. As I stood just outside the room, I asked Mr. L, "Was that doorbell on the T.V.?"

This little four year old, that was caught up in his show, got up from the couch. He walked over to the television and calmly looked behind it. He turned toward me and said, "No. There isn't a doorbell on the T.V."
