A teacher once told each of her students to bring a clean plastic bag and a bag of potatoes to schoo1．For every person they didn’t want to forgive in their lives，they were told to choose a potato，write on it the name and the date，and put it in the bag．Some of their bags were very heavy.
They were then told to carry this bag with them everywhere for one week．They would put it beside their bed at night，on the seat when sitting in a car or on a bus，and next to their desk at schoo1．
Days of carrying the bags around with them got the students to get to know what a weight they were carrying in their hands．And they had to pay attention to it all the time (1)__________they didn’t forget it．(2)As time passed by，the potatoes went bad and smelt very terrible．
Too often we think of tolerance(容忍)as a gift to other people，and it clearly is for ourselves! Sometimes we choose to keep our sadness in our hearts，we have to carry them around all our lives．If everyone learns to forgive，our world will become a better one．
