There are people who are never content, never appeased, forever dissatisfied—who continually look to what escapes them, convincing themselves that if only they could attain that one desire outside of reach they would be happy.  It seems almost pointless to give to these people because their eyes immediately shift from the gift to stare miserably at the portion held back.  Their wants, demands, expectations, appetites are never satiated, thus they refuse to be happy.  And you cannot make them so.
