I like to see people happy, so I like to help others.I joined the volunteers to become one of them. One day I received a task: come up with a way to make people around you happy.I was eager to come up with a way to satisfy me, so I went to the square.The square was a sea of people. I took out the paper I had prepared and put it in front of me.One after another, but they are not particularly interested in, gradually I began to doubt myself.At this time, a little girl came, she smiled and said to me: "sister, you can teach me how to tie shoelaces, I want to prove to my mother, I also do a good child" "Of course, it's my pleasure".After teaching her, my little sister smiled at me and opened her arms to hug me.I gladly accepted and she held her back.People around us looked at us with a happy look, but also began to move, one after another around me full of people.Someone whispered the words written on the paper: free hug.The next square appeared such a picture: we embrace each other, although we do not know each other, we are happy to laugh, and even the birds should follow.Come back to home. I was lying on the bed, looking back on the day, I smiled.
