One morning more than thirty years ago, I entered the Track Kitchen, a restaurant where everyone from the humblest(卑微的) to the most powerful came for breakfast. I notice an empty chair next to an elderly, unshaven man, who looked somewhat disheveled. He was wearing a worn-out hat and was alone. I asked if I might join him. He agreed quietly and I sat down to have my breakfast.

We cautiously began a conversation and spoke about a wide range of things. We never introduced ourselves. I was concerned that he might have no money and not be able to afford something to eat. So as I rose to go back to the counter and buy a second cup of coffee, I asked.

“May I get you something?”   “A coffee would be nice.”

Then I bought him a cup of coffee. We talked more, and he accepted another cup of coffee. Finally, I rose to leave, wished him well, and headed for the exit. At the door I met one of my friends. He asked, “How did you get to know Mr. Galbreath?”

“Who?”“The man you were sitting with. He is chairman of the Board of Churchchill Downs. ”

I could hardly believe it. I was buying, offering a free breakfast, and feeling pity for one of the world’s richest and most powerful men!

My few minutes with Mr. Galbreath changed my life. Now I try to treat everyone with respect, no matter who I think they are, and to meet another human being with kindness and sincerity.
