A teacher asked her students to play a game. The teacher told each child to bring a bag with a few potatoes. Each potato was given a name of a person that the child hates, so the number of potatoes that a child would put into the bag would depend on the number of people the child hates.
Some children had two potatoes; some had three and others even had up to five potatoes. The teacher then told them to carry the bag wherever they went for a week. As the days went by, the children started to complain (抱怨) about the unpleasant smell coming from the rotten (腐烂的) potatoes. And the students with five potatoes also had to carry heavier bags. After a week, the teacher asked," How did you feel!?" The children started complaining about the trouble they had to go through when they had to carry the heavy and smelly (难闻的) potatoes everywhere they went.
Then the teacher said," This is the same situation when you carry your hate for somebody inside your heart. The smell of hate will close your heart and you will carry it with you wherever you go. If you cannot stand the smell of rotten potatoes for just one week, can you imagine what it is like to have the smell of hate in your heart for your lifetime? So learn to forgive(原谅) other people from now on and I am sure you will have a happier life."
