This afternoon I went to see my grandfather by a bus. It was very

crowded and I had to stand. Besides me there was a woman held a little boy

in her arms. In front of her, a young man occupies two seats, pretending to be

sleeping. I heard the little boy curious asking his mother, “What’s wrong with

the uncle?” I had thought if perhaps the woman would blame the man.

Beyond her expectations, the woman answered with a smile, “Be quiet. This

uncle must very tired because of hard work.” The young man must have

heard the word. His face turned red and offered one seat for the woman at once.
