why we should say "Thank you" to others?
"Thank you" is a word to express one's politeness to other people. If someone helps you out of trouble, you should say "Thank you" to him or her. That is your responsibilities. Imagine, if you do some good things, no one say "Thank you" to you, what kind of taste you feel? Meanwhile, everyone in the world don't say "Thank you" to peole who help them, then nobody want to do good things and help others.
