manner

I think its very important from childhood to teach a child good manners.In the future for him its very important,because educated people perceive differently.Today I meet these people are less and less. Now I live in a dorm, and when I'm going to sleep, on the street is going to what some company that bothers me, they are very loud talking, playing the guitar, swear. It is very annoying.Or, for example, in public transport, very discourteously behave drivers and cashiers, They are very careless about human life. Bad manners are everywhere. So we have to be very serious about this treat, and try to be a good example for the younger generation, as children absorb everything like a sponge.
