The other day，I decided to teach my son about the power （力量）of small acts of kindness．He had won some candies in a prize machine in the local supermarket，so I asked him if he would like to share his candies with others．He was hesitant （犹豫的） because he is a shy little boy，but he said yes after I encouraged him a bit．
