We live in a happy and harmony world.We can't live without others' help.And we should help others in return.I think that if we always show a giving heart instead of a receiving one to the people around,then we will receive more helping hands when it is really needed.As a matter of fact,in my viewpoint,I do hold that we should give without any expectation of receiving in the future.After all,it is kind of good deed and can make our lives more meaningful.Remember that giving and receiving are the both sides of the same coin.So anyone who is willing to give today,I suppose,will definitely receive more in the future.
