Ask to write a 200-word composition that describes not giving up your seat

Today, my mother and I happily went to my aunt's house to send gifts. On the bus, I heard the broadcast: "Please give your seat to the disabled, the elderly, pregnant women and people with babies." This sentence let me know how to do it. Suddenly, on the road ahead, the car stopped. An old woman with silver hair came up with a cane in her hand. At this time, the car was crowded with men, women and children. Needless to guess, grandma must have nowhere to sit. "Please give your seat to the disabled, the elderly, pregnant women and people with babies." This sentence still rings in my ear from time to time. I turned to look at the passengers present. Instead of moving, they laughed loudly in the car. I thought to myself: a man is a man, dare to do it, but why don't the passengers give up their seats to this old woman? Where is this the hero of China people?
