In our life, there are always some people who are ordinary and noble. It is these people who make us happy and make society better. And I met a man-a strange little boy, and his behavior was very warm.

It was cold that day. I went to the interest class by bus, and there was a thick fog on the window. As the bus stops, the bus stops and the door opens. The surging crowd crowded in, and the carriage was soon packed. When the car door was about to close, a hurried voice came from a distance: "Wait a minute!" " Wait a minute! ..... "I looked out of the car door and saw a 60-year-old grandfather panting and running into the car.

Grandpa is wearing a thick cotton-padded jacket, hunched, wrinkled and gaunt. Looking around, I found no handrails. The car started, and his body kept shaking, stumbling a few steps from time to time.

After watching this scene, I can't help thinking: in such a crowded carriage, will someone give his seat to grandpa? At this moment, a little boy stood up and said loudly to his grandfather, "Grandpa, come and sit down." This is a child about eight or nine years old, carrying a schoolbag, wearing a pair of glasses and cutting a person's head.

"Oh, thank you, little friend!" "You're welcome." The little boy replied with a red face, got up and helped the grandfather sit down, and stood beside the seat himself. The car was driving on a bumpy road, and the little boy kept shaking with the car. Grandpa stretched out his wrinkled hand and gently pulled the little boy over and sat him on his lap. They both smiled at each other.

Looking at the grandfather and the little boy, I instantly felt a warm current flowing in the carriage.
