Common courtesy is very uncommon. Do you ever notice that when somebody thanks you, you actually feel good? And yet it is so rare that people actually do it, particularly from the heart. It is even rarer when you get a “thank you” note in the mail. And if you get a “thank you” note in the mail it makes your day. You save it and read it again and again. Why, because “thank you’s” touch people’s lives. So my recommendation is to listen to what your mother told you when you were little and write a “thank you note.” Make somebody’s day and show that you care. That small bit of effort will brighten their day, bring a smile to their face and you will be differentiated in their minds at which point the whole world gets more special. So, remember, thank you very much!
