     American people like to say "Thank you" when others help them or say something kind to them.People

of many countries do so, too.It is a very good habit.

     You should say "Thank you" when someone passes you the salt on the table, when someone walking

ahead of you keeps the door open for you, when someone says you have done your work well, or you have

bought a nice thing, or your city is very beautiful. "Thank you" is used not only between friends, but also

between parents and children, brothers and sisters.
