Mister Rogers arrives with a paper tablet and pencil which he uses to show the different between letters and numbers that look alike. Mr. McFeely stops by to demonstrate a chalk board and to deliver a copy of the book from the previous day which has been corrected. Before Mr. McFeely leaves, he and Mister Rogers watch a film about how people make books. In the Neighborhood of Make-Believe, Audrey Duck is nervous about reading her poem in front of others as requested by King Friday. She and Miss Paulificate sing It's Nice to Be Ourselves before Lady Aberlin arrives and sings a similar song to X the Owl. X wants to make Audrey's poem into a book to show he is sorry for his mistake from the previous day. At the school, the children learn about making mistakes. Back at the house, Mister Rogers starts to sing It's Nice to Be Ourselves before Mr. McFeely returns with a real duck. Part of the "Mister Rogers' Neighborhood" series.
