     A few years ago when my daughter was about two years old,  I went through a difficult time.My

marriage was in trouble,  I was pregnant (怀孕的) and not particularly well and I didn't have much money.Looking back I think I was also a bit depressed,  but I had to get on with taking care of my daughter the

best I could.

     One day I thought I would take my daughter to the park for a nice day as she liked there,  and I

thought it was a nice thing to do.I decided to walk because the bus was expensive,  so it took us a long

time to get there.When we finally got there,  immediately my daughter began to cry.She was cold,  she was thirsty,  and she wanted to go home.To be honest,  I had not prepared properly.I didn't even have any

money to buy a drink or to take the bus back home.I was so frustrated and cross with myself that my

dream of a nice day failed.

     I started walking back home (it was nearly 2 miles),  and my daughter would not stop crying.I felt so

miserable and cross with myself and my life that I started crying too.

     At that point a car stopped and a gentleman offered us a lift.He took us home,  and seemed really

concerned-he even offered me all his change!   The kindness of this stranger to a stranger like me really

made me feel better.I never saw him again and I don't know who he is but he really helped me out that

day,  so I just want to say thank you.
