    A teacher once told each of her students to bring a clear plastic bag and a large bag of potatoes to school. For every person that the students refused 1.(forgive) in their life, they 2.(choose) a potato, wrote on it the name of that person and the date, and then put it in the plastic bag. Some of their bags were quite heavy.

They were then told to carry these bags with them everywhere for one week, 3.(put) them beside their beds at night, on their car seats 4.driving, and next to their desks at work.

During this time, as they carried the bags around with them, they realized 5.a weight they were carrying, and how they needed to pay attention all the time, so as not to forget them or leave them in 6.(embarrass) places. Of course, the potatoes were becoming rotten, and 7.(smell) very bad.

This is the same 8.the price we pay for keeping our pain and 9.(happy) with us! Forgiving others is not only a gift to them, but also a very good gift to 10.(our)！
