In her diary, how does Anne Frank make a distinction between Mr. Dussel and Mr. Frank? Mr. Dussel is generous and willingly shares food with the others, while Mr. Frank is selfish and often hoards food. Mr. Dussel is fussy and argues with everyone while Mr. Frank is even-tempered and eager for peace in the Annex. Mr. Dussel encourages Anne's studies by letting her use the desk twice a week, while Mr. Frank instructs Anne not to bother Mr. Dussel. Mr. Dussel gets along with everyone in the Annex, while Mr. Frank is argumentative and difficult to live with.
