If you have ever wondered if saying “thank you” to someone can make a difference, watch this video. All it took was a short and sweet note to the mail carrier woman to thank her for her hard work during this difficult time, but it brought her to tears. The note didn’t come with some huge gift or wad of cash, just simple words of gratitude. We have no idea what others are going through or the difference that a kind word or small gesture such as a heartfelt smile can make to someone’s life. Here we are able to see its impact and it is a beautiful reaction to watch.
