Albert's sister, Maria, is born when he is two years old. Everyone calls her "Maja". Albert does not quite understand what a new-born baby is. He thinks that he has got a new toy and is disappointed when he sees his sister for the first time. "Yes, but where are the wheels?" he asks. Maja is naturally not a new toy car but his younger sister and he has to accept this. Albert is sometimes bad tempered. "At such times, his face turned yellow and the tip of his nose was extremeley white!, Maja said later. He would then hit her on the head with his heel. In spite of this, Maja and her brother got on well throughout their lives. Later, they even lived together in a house and Albert took loving care of his sick sister.
