When I was on a business trip, I received a phone call from an acquaintance who said that the daughter of a friend of his had been admitted to a university in my city and had been on a semester. I hope I can take care of her when I am free. I promised, but I didn’t take it seriously. After returning to the company, I was busy with the project and didn’t take care of it. One day, I got a call and asked if I was so and so. There was a very young girl voice on the phone. I immediately realized that this was the little girl.
