Then I began to tutor a rich man's children. People have mobile phones since junior high school. At that time, mobile phones were still a rarity. He has a mobile phone belonging to Motorola, and his envious eyes are always in my eyes. I taught him for a summer vacation and earned money for next semester! In this way, I have been a tutor until the end of senior three!
Now that I think about it, it's really a good memory.
