The tomcat stretched lazily and then licked his paw. “I’m taking off for a bit,” he told his son. “You’re going to search for some milk, aren’t you? Can I come along?” his son asked. “I’m thirsty, too.” “Not today,” the tomcat answered. He had no intention of introducing his son to the porch step where the farmer’s wife set out a bowl of milk for him as soon as the sun was at its highest point in the sky. If he came, I’d have to share my milk. No way!!
