Caillou sees the school bus go by his window every day and he wants to go on a ride with it. He asks Dad when he can ride on the school bus and Dad says that he can't until his next birthday. Caillou, though, is 4 and so he wants to go on the school bus (all together now, really whiny) NOW. Dad says that they can go and see the school bus up close. They get up early the next day. Sarah asks Caillou if he's coming on the bus. Dad says no, but then the bus driver sees Caillou's Dad and realizes that he knows him. Dad greets the bus driver as Mr. Washington. The driver says that he looks forward to taking Caillou to school on the bus when the time comes. He offers to let Caillou ride on the bus the next day, if he can clear it with his boss. The next day, the bus comes and Mr. Washington tells Caillou to get on the bus. Caillou goes to the school and back. Dad has Caillou thank Mr. Washington. Mr. Washington says that he'll see Caillou after his next birthday. (thetvdb.com)
