Can't I have a ride now, Russ? You said it would be my turn after Mun Bun. "Yes, but, Margy, I haven't had enough ride yet " declared Mun Bun. "But when can I get in and have my ride?" The three little children, two girls and a boy, stood in front of their older brother, Russ, watching him tying an old roller skate on the end of a board. "Can't I have any more rides?" asked the smallest boy. "In a minute, Mun Bun. As soon as I get this skate fastened on," answered Russ. "You rode so hard last time that you busted the scooter, and I've got to fix it. You broke the skate off " "I didn't mean to," and Mun Bun, who was called that because no one ever had the time to call him by his whole name, Munroe Ford Bunker-Mun Bun looked sorry for what had happened.
