Prejudice is Behavior

It would seem by now, I suppose, that Time would heal. Tens of thousands of years of civilization (and even more so with the pre-human era) has slowly, patiently, in the unwary cusp of Time's hands, brought us to this point in which we are all living. Now we're in the 21st century and showing signs of settling in, yet no avenging of purposeful human evil and fewer memories of its victims dead or alive. If any mention opportune itself, the human being is immune to Time's healing properties; a species of mammal that can form concepts, language, learn/adapt, imagine possibilities and remember has learned to turn Time into a device which both alienates and binds us to the industries of human endeavors.
Humans have been here a long time and the wounds are still fresh. Prejudice has withstood the influence of Time. We all see it. We all have a little of it repressed within. For most of us it becomes "behavior" or habit.
Above is an aesthetically unremarkable photo of a man seated at a table. he appears to be focused on the novel before him; older than fifty, younger than seventy. This kind of man might live in your neighborhood or apartment complex. You might even open the door for him or offer your seat to him if you're riding the bus. A harmless looking man.
He came in after I did. I already had my food and was reading a book called: The Pleasures and Sorrows of Work by Alain De Botton. I was there of over an hour, too wound up from work to go home, let alone cook. So In and Out was my saving grace. When I had finished, I cleaned after myself (a habit from Mom), threw my trash away and left. As I was bicycling away I happen to see This man rush from his previous spot over to where I sat, carrying a handful of napkins. What I witnessed stunned me. I couldn't believe what I saw: The Old man scrubbed the table with the napkins. I mean, scrubbed hard! He scrubbed the table top then all four edges of the table top, under the table. Stopped briefly to fill his cup with water at the soda fountain. Returned and scrubbed the seat detailing every inch of it. It didn't end there. He poured the water on the floor and used the napkins to scrub where my feet were. It was probably the most disturbing sight I've seen in recent years and the most hurtful. He turned away the helpful employees trying to assist him and used the remaining napkins to retrieve the trash and threw them away. After this he finally sat down. The whole event took about fifteen minutes. Prejudice is behavior, not always accusation, not always stereotypes. We both had our books. We both ate our burgers. We both shared the same space yet I was considered inferior and unclean from a man that may have been tasked with the unfortunate duty, in the golden years, of scrubbing the pool after we used it or mopping the floors after we walked on them...
It would seem that Time doesn't live long enough to heal human beings of this kind of behavior. Six hundred years is still not enough to encourage extinction of human evil. My only prayer is that this man dies with all his hatred. Our world has more than it will ever need.
