問２の解説を詳しくお願いします。

次の英文は、裕太(Yuta)が書いたものである。これを読んで、後の各問に答えよ。 "So, let's continue making an introduction about your fathers," said our English teacher, Mrs. Yashima one month ago. This class was Dmind-numbing, and I was thinking of the way to kill the time during the class. 4 I didn't know much about my father He was always busy working, so I didn't have any memories of playing with him at all. He came home late at night, woke up earlier than me, and left for his workplace without having breakfast. On weekends, he was always watching news programs which never interested me. When I looked out of the window, a friend of mine who was living near my home was playing catch with his father, and I projected myself on him. When we were having dinner, he never asked me any nice question. He always said to me, "How are the school and the club going?" I only said, "Not bad," because I thought that he had no interest in my school life or club activity. I didn't know about my father well, but I remember the other face of him. He sometimes repaired things in our home such as the TV set, chair, or bicycle. I wasn't interested in it at all until a neighbor told me a story about my father. She always took care of me when my parents were busy. "Your father is a good person," she said. "He always repairs broken things with a smile. It was just like magic." And she gave me some cookies. I knew about my father a little. The other day, I visited a factory as a part of social study class, and a man spoke to me, "Oh, your last name is..., are you his son? When I was working for another company with him, he took good care of me. He sometimes scolded me, but taught me a lot of things. So, I respect him so much." I knew about my father well. When I told my father about the man, he said to me, "Keep the friendship all the time. If you give a hand to someone, the person will give you a hand back someday. Just remember it." At that time, I understood that my father was a hard worker and he was respected by many people. Though he was a serious and silent person, I felt I knew him for the first time. 2022(R4) LAMANG
