Today is my father’s birthday. To celebrate his birthday, I went to a shop and choose a present for him. After that, I went home by the train. On the way, I was imagining how happily my father would be when he accepted the present. The train got to the next stop before I knew it. An old lady got the train. Every seat was taken, but she had to stand with two heavy bags in both of her hand.

After an immediate hesitation（犹豫）, I gave my seat to her and he was grateful for all what I did.

In my opinion, give others a hand whenever they are in trouble not only brings happiness to the ones who receive it but also to the ones who give it.
