People like to say "Thank you" when others help them or say something kind for them. It is a very good
habit.
You should say "Thank you" 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 beautiful. We
can use "Thank you" not only between friends, but also between parents and children, brothers and sisters.
"Excuse me" is another short sentence we often use. When you hear someone say so behind you, you
know that somebody wants to walk pass you without touching you. When others are talking, if you want to
speak to one of them, say "Excuse me" first, and then begin talking. You should also do so when you begin to
cough or make any noise before others.
