About three months ago, I took my nine-year-old son to Qingdao, Shandong, It was a special trip.
When we got there, my son was very (excite) because it was the first time for him (take) the subway.
When we got on the subway, I found It was (fill)of people and we had to stand. However, a boy wearing sports clothes asked me to sit in his seat. He also advised his friend siting next him to do that. So it would be easy for me to take care of my son.
I said "Thank you" as he (stand) up and then we sat down. When we got the subway, the kind boy (say)goodbye to us.
Later I lost my wallet while I was (shop)in the city center. (luck) a stranger found it and r it to me.
These kind people really made our trip to Qingdao very unforgettable. I told my son that we should try our best to help the people in need in return.
