Very true, along with giving others respect.

A quick story. I delivered mail to a man who worked in the typewriter ribbon factory in town. He spent decades down in the basement of the plant grinding up pigment and making ink. His skin looked blue from the pigment getting into the pores. I had a letter he had to sign for so I drove up to his house. It looked like a converted tool shed and it was falling apart. I knocked on the door and he answered it and seemed scared about the letter.
The letter was from the town to let people in the area know they were going to be doing some work in the area. I told him about it and not to worry. I then said to him, "Sign here on the line, sir."
He looked at me and began to cry. I asked him if he was okay and he said "You are the first person to ever call me sir." That made one hell of an impression on me, how a few kind words or sign of respect can affect someone.
