S1·E48 Caillou's Getting Older!

Caillou is very curious when he finds a dead bird in the garden. He wants to know why it died. Dad explains that it probably got too old. Caillou thinks about that and begins to worry about getting too old himself. He tells Mom and Dad he doesn’t want to get any older because of what happened to the bird. They reassure him and he agrees he has plenty of time to get older.
