Anne continues to keep busy by studying French, math, history, and shorthand. She writes that she is getting along with her mother and Margot better. The two sisters agree to let each other read their diaries. Anne asks Margot what she wants to be when she grows up, but Margot is mysterious about it.
Anne and the others in the annex have a scare when a carpenter comes to fill the fire extinguishers without advanced warning. They hear someone banging on the bookcase and they think the carpenter is going to discover them, but then they realize it is Mr. Kleiman, a man who helped them hide, trying to move the door since it is stuck. Miep Gies, a worker in Mr. Frank’s office, spends a night in the annex along with her husband, Jan. Anne enjoys having the visitors around.
Later in the week, Mr. Frank becomes ill, but the family cannot call a doctor. That weekend, Bep Voskuijl, another worker in Mr. Frank’s office, stays in the annex. Anne writes that she is very excited because she thinks she is about to get her period. In a note she adds to this section in 1944, Anne writes that she cannot believe her “childish innocence” from that time, and she calls her descriptions “indelicate.” She also mentions how the whole time she has been in hiding she has longed for “trust, love and physical affection.”
Anne reports on some of the British successes in Africa and puzzles over Churchill’s famous quotation about the war being at “the end of the beginning.” Mr. Frank recovers from his illness, and Peter turns sixteen. The residents of the annex also agree to take in an eighth person, and Anne is very excited at the prospect of a new addition.
The newcomer is Albert Dussel, a dentist who is married to a Christian woman. Mr. Dussel is excited when Miep tells him of the hiding place, but he asks for a few extra days to put his accounts in order and treat some patients. Mr. Dussel meets Mr. Kleiman at an appointed time, and Miep then leads him to the annex. Mr. Dussel is surprised to see the Frank family because he had heard they were in Belgium.
The van Daans give Mr. Dussel a tongue-in-cheek list of rules upon his arrival. He shares a room with Anne and tells her about the atrocities committed outside, including the murders of women and children. Anne thinks that they are lucky to be in hiding, and she thinks of the suffering her friends must endure merely because they are Jewish. Anne writes that she is very upset by the news, but she resolves that she cannot spend all her time crying. The loneliness of the attic makes her unhappy.
