A man learned shortly before quitting time that he had to attend a meeting. He tried unsuccessfully to locate his car-pool members to let them know that he would not be leaving with them. Hastily he scribbled a message to one fellow and left it on his desk: "I have a last-minute meeting. Leave without me. Dave."
