Parents lack play a role in educating children on courtesy because they are too busy with their respective careers to ignore their responsibilities. Often do not have time to see children grow up and guide them in terms of emotional development. The parents do not raise them the way it is supposed to or have bad friends that give them the wrong meanings of the values, or they do not even put them in practice anymore. if in the education that they give them to the children there was more love and interest, then our place would not be like it is now, with drug traffic, bullying, robberies and even killing. Parents spent most of their time for work, economic problems, stress or sometimes by the simple act of not to create a fight, leave to one side for education of their children and in lots of cases, they think they can replace the love with material things, but the love from their off springs.
