From my perspective,we should try to forgive our friends who have done something unpleasant to us or even offend us,because no one is perfect.In the meantime,we should learn to value true friendship and be grateful to our friends who have helped us,for which a friend is a supporter who comes to our help when we meet with difficulties.In the company of our friemds we will never feel lonely.Therefore,we should make friends with those who are helpful and trustworthy.A friend in need is a friend indeed.
