He goes over and asks him if he can help, but the boy just ignores him. This bothers Caillou and so he goes to his mom, who talks to the boy's mom standing nearby. They just moved in and the boy's name is Rob. She explains that Rob is deaf and so he can't hear Caillou. Caillou doesn't get it at first though. He thinks that perhaps if he were to talk really loudly, Rob might be able to hear him. It doesn't work, but eventually Caillou starts picking up on Rob's sign language. Rob's mom agrees to let Rob come over to Caillou's. They play for a while and Caillou wonders about Rob's sign language. It's explained to him and then Rob has to leave. He parts, having made a new friend. "A Frog in Caillou's Throat" (a42 wip title: "Let's Play Charades" ) Repeat of Episode 13 , Segment #1.
