Writing and reading are the focus today. Caillou is all excited to read the weekend paper with Daddy, but the wind and a very mischievous cat delay his reading time. With a little patience and persistence, Caillou finally gets to enjoy his favorite comic strip. Later, when Mommy is upset because the mailman only brings bills, bills, and more bills, she tells Caillou that it would be great to get a nice letter for a change. Caillou and Daddy decide to write Mommy a really nice letter, and the next morning they give it to the mail carrier to deliver. Mommy is thrilled! On another day, Sarah invites Caillou to a little brother or sister day at school. The school is big and Caillou is a little afraid. But with Sarah's help Caillou has a lot of fun.
