What is the to be polite?

Nowadays people is very rude.Also older people says"Where is the old days?". I think it is related to be polite.Because if people to be kind, everything is resolved. To be kind very important. For example, if everyone is helpful there is no such think as poverty in the world. So everyone will be happier. Like old times.Also if everyone to be kind, leaves a good impression to tourists.It is important for country. So mean of the to be kind; means a better world, happier children and peaceful older people.To sum up,if we want a better world we must be kind
