Write about an incident in your life

Hi guys, my name is Dũng, i'm 17 year old and to day i am going to tell you about an icident that i will always remember. It was one afternoon, due to the raging covid epidemic, I had to study online at home. At that moment my phone rang and I quickly picked it up. It was her grandmother who suddenly had a severe fever because she was old or feverish, so her parents bought medicine for her and told me to take it away in the morning. But because I was so busy studying, I forgot to bring her medicine. At home, I only have one bicycle, I don't think much of it. I put a cigarette in my backpack and drove off at a very fast speed. When I was about to go to my grandmother's house, due to cycling too fast, my backpack broke and fell on the road, at that time I didn't know anything and continued to pedal suddenly a voice called, calling me to turn back, I looked in a panic. When I saw a tall, thin, handsome adult calling me back and holding my book bag in my hand, I quickly looked behind me and saw that my bag was gone. I hurriedly stopped the car and pedaled quickly to the young man, I thanked him, then took my backpack and continued, because I was in a hurry, I didn't think much of him. After everything was fine, I started cycling home. The autumn air is cool, and quiet. I listen to music while walking, feeling very peaceful and I remember the young man who was lucky enough to have him and my grandmother had medicine to take. And I think in this life there are still a lot of good people that we should respect. I went home to eat and told my parents about today my parents laughed and didn't say anything but they also thanked me for being a good person good boy. To summarize. Those are the situations that I have the hardest time to forget.
