I just went to get some coffee at Dunkin Donuts and there was this cute, elderly couple sitting at the table right by the door. I walked in and the man said “good morning” to me. As I was walking out, I went to tell them “have a nice day” and the woman said it to me at the exact same time.
It is the little gestures in life that tend to have the greatest impact. Imagine what we could do in the world if merely saying good morning brings a smile to someone’s face.
