Mr. Van Daan was caught stealing bread and that caused a conflict among the families in the annex.
Explanation:
Act 2 Scene 3 of Anne Frank's diary shows Mr. Van Daan stealing bread when others were asleep. He stealthily went down the stairs to the main room, where Mr. Frank, his wife and their daughter Margot were sleeping. When he opened the safe to collect the bread, there was a creak sound which was heard by Mrs. Frank. Mrs. Frank alerted the other members of the annex and created a huge fuss about the act. She asked the Van Daan's to leave the annex and even offered to give them some money to leave.
A good news from Miep about the invasion at Normandy eventually cheers the entire annex up. Mrs Frank feels sorry for her action and Mr. Van Daan who was ashamed was pacified by the others.
