There are all kinds of persons in the world,but every person has his own character.So there is diversity of characters.
For example, some people are always happy no matter what happens.They are generous and are ready to help others.Such people are welcomes wherever they go,because they may bring pleasure to others.
Another kind of person is the disagreeable kind,They are weak in character,and they are easily disappointed when they are in trouble,They are easily hurt by others' words,while they often offend others' feelings by their eccentric dispositions.Wherever they appear,eventhe air becomes unpleasant.
