The Diary of Anne Frank by Anne Frank

Dearest Kitty, For the last ten days Dussel hasn't been on speaking terms with Mr van Daan, and all because of the new security measures since the break-in. One of these was that he's no longer allowed to go downstairs in the evenings. Peter and Mr van Daan make the last round every night at nine-thirty, and after that no one may go downstairs. We can't flush the toilet any more after eight at night or after eight in the morning. The windows may be opened only in the morning when the lights go on in Mr Kugler's office, and they can no longer be propped open with a stick at night. This last measure is the reason for Dussel's sulking. He claims that Mr van Daan ticked him off, but he has only himself to blame. He says he'd rather live without food than without air, and that they simply must work out a way to keep the windows open.

'I'll have to speak to Mr Kugler about this,' he said to me.
