LOVE FORАRT
Joe and Delia both loved art. Joe came to New York to study painting; Delia left a little town for New York to study music. Joe and Delia met at the friend` s studio, and a year later they got married. Joe and Delia were very happy, but one day they found that they had no money. Delia decided to give music lessons, and a few days later she came home very pleased with herself. “Joe, dear”, she said. “I have found a pupil. The family is rich, they` ll pay me five dollars a lesson!” However, Joe was not happy about that. He didn’t want his wife to work, he wanted her to study and be a famous pianist.
A week later Delia brought home 15 dollars for three lessons. To her surprise Joe put four five-dollar bills on the table too. He said that he had sold one of his pictures.
One Saturday evening Delia came home late, she looked very tired and her right hand was banged. Delia said: “My pupil’s family invited me to dinner after the lesson and the girl spilled some hot sauce on my hand. She was very sorry about that. “At what time did you burn your hand, Delia?” Joe asked her. “About five. The iron…I mean the sauce...” “Darling,” Joe took her hand in his. “Where are you working?” And she told him the truth. Delia couldn’t find any pupils and as she wanted Joe to study painting, she had to work in a laundry. “How did you know I wasn’t giving music lessons?” she asked. “I sent up these bandages this afternoon for a girl who had burnt her hand with an iron. I am working in the machine room of the same laundry.”
