It was several years ago when my wife asked me to meet her at the local department store on Black Friday morning. They had advertised a bike that she wanted to purchase for our son. We stood with a very large crowd, waiting for the manager to blow the whistle. After a while the whistle blew. It was like throwing a basket of chum into a tank of sharks. I told my wife that if we obtained a bike, fine, but if we did not, I was OK with that too.

As the number of the bike boxes began to gradually decrease, I saw my opportunity to wrap my hands around the corner of one of them. I lifted it and suddenly felt some mild resistance. I looked up to see one of the largest men I had ever seen in my life. Frightening was not enough to describe his presence. He was decorated with numerous leather belts with metal buttons around both arms and even his neck.

I started to loosen the box but he gently pushed it back in my direction and back into my hands. He then directed it to my shopping cart. He looked at me, smiled, and said, “Merry Christmas. ”

My wife and I went to the checkout, paid for the bike and went home. All the way home I was thinking that this moment was by far the best Christmas gift I had ever received. The kindness of a human heart in a simple act of a stranger broke all preconceived notions I might have had. I will never forget it.
