Detailed Answer :
Alfred Dussel was a dentist and an acquaintance of the Franks who hid with them in the annexe. He shared a room with Anne, who suffered the brunt of his odd personal hygiene habits, pedantic lectures, and controlling tendencies. He never cared for the feelings of others and turned out to be an irresponsible person. He was the eighth entrant of the house. Anne disliked him for his self-centered nature. As he used to scold her and made it a point to tell her about her shortcomings. Anne had shared her room with him but when she asked him to let her use the table for two more hours, he bluntly refused, giving Anne a shock.
