Good manners are very inportant.(well old peoples think that)  If you don't have good manners, people would maybe think that you are weird, and they will maybe stay away from you.

That to have good manners are really important. It's mostly old people that have the best manners, because they think it's much more important with good manners then for example me and other young people. We don't care so much about if we have good or bad manners, we can for example eat with the tv, and have you somtime seen a old peson eating with the tv? 

And we are talking very different from old people. They are using nice words all the time. They use words like please, thank you, sorry can I help you?, excuse me, how are you today and Mr., Mrs Sir and madam. We younger are not using so much that kind of words,we are talking more "cooler". And older people have much better manners when they are with others peoples. So when they wisit other they try to have so good manners as posible,and young people dont care so much.

That I trying to tell you is that old people have much better manners because they think it's so important to have good manners. And we younger don't have so good manners, but of course can we younger have good manners, but not so good as old people.
