Everyone wants to be polite,but it is not so easy.We must be care of everything in life.
First,say "hello" to people you meet,not only to teachers,but also to your friends and your classmates,and maybe your neighbours.Second,help the others as much as you can do.Then everybody will like you.Third,don't laugh at the others.That will be very hurt and impolite.Fourth,never ask the other about their personal imformation.If others have something cannot tell,that will be very embarrase.
