A kindergarten teacher had the students bring potatoes labeled with the names of people they hated as part of a game. The students carried the potatoes with them for a week, complaining about the smell and weight. The teacher then explained that carrying hatred in your heart is like carrying rotten potatoes, and asked if they could tolerate hatred for a lifetime in the same way they couldn't tolerate the smell for a week. The moral is to throw away hatred and forgive others.
