If one gives back what he has found,it should be a happy thing for both finder and the owner of the lost property.However,it reality,embarrassment and unhappiness de exist between them. Positive:Of course.It is reasonable for finder to ask for rebound after he gives back what he has found.Because,the process of the finder picks the property and gives it back costs the finder time and vigor.He deserves certain compensation. Negative:He should not ask for compensation.From the angle of economy,to pay for the lost may be reasonable.But if everything is measured by money.It is no doubt that the spirit of the society will lose,and many noble actions will become philistinism. Should we canonize th give back what we have found?Is it reasonable?Is it good to ask for some compensation as a common social action?
