violence in school

the children in Japan, the number of violence is increasing. some children fight each other, and more worse the children kill somebody who are their friends. why do they do that until killing friend? i think that the children do not know LIMIT of violence. because of not knowing the limit, they get to stab somebody. moreover, the children do not have any patience. they do not patient, they appear their emotion like violent, and they get to attack people.

now, how can we save or stop their violence? i insist that the children need more time to sleep. they get enough time to sleep, they can relief their stress. and then, the parents have to express how much they love children. if parents love children, the children can get the love, and they get to know how to love people. it is very important ability as a human. so sleep and love are good way to stop violence.
