The last Monday in September marks the premiere of a new annual National Thank You Day. Here’s why it’s necessary: A survey conducted by The Emily Post Institute found that while 87.3 percent of Americans say they are bothered when people don't say thank you, 90.2 percent feel that they don't say thank you enough.

The survey also found that saying “please,” “thank you,” and “you're welcome” are the manners Americans need to observe most, followed by practicing patience and politeness while waiting in lines.

To celebrate this day, say thank you to as many people you can, in as many ways you can. I assure you, when you express your appreciation to someone, the results will be unimaginably great.
