Thinking about Mr. Glenn, my neighbor, my friend, and a father figure that I always wanted always brings a smile to my face. I often have trouble describing what kind of person he was because Mr. Glenn was so unique. I remember once telling him that he is truly ineffable.
Now, Mr. Glenn was an eighty year old, tall, bald headed man with a gray beard. He has two kids who are now in college and many grandchildren. Often when I was with Mr. Glenn, I have the hilarious notion, of being with Bill Crosby. I can easily imagine this because they both used humor to overcome the many personal obstacles that stood in their way. Bill Crosby once said, "Through humor, you can soften some of the worst blows that life delivers. And once you find laughter, no matter how painful your situation might be, you can survive it."
Like Bill Crosby, Mr. Glenn never gave up, was a friend to all, and a generous and caring person who prided himself in helping the community. "Mr. Glenn was a great guy and an even better neighbor. He was always trying to help someone. He was truly a special person", said Tonya Smith, a neighbor of Mr. Glenn for almost twenty years. In addition, Mr. Glenn was also a practical jokester. He would say and do anything to cheer you up. I remember one day, when I was having a bad day, he actually came outside with his shoes on the wrong feet, which really made me laugh. During Mr. Glenn's life, he struggled with discrimination in his childhood, the death of his wife later in life, and then being diagnosed with cancer. None of which could destroy his spirit.
I first met Mr. Glenn when I was sixteen. My family and I had just moved into the neighborhood and were going around the neighborhood introducing ourselves to our new neighbors. After knocking on at least ten doors, we finally got his door, and he answered and identified himself as Mr. Glenn. He was very nice and shared lots of funny stories with us about the neighborhood and the neighbors. This story in particular is the one I remember the most; he said, "This is a great neighborhood and the neighbors are very friendly, but be very careful where you put your trash cans at night because once in a while, these high school kids will come and grab the handles on trash cans while driving and going thirty or forty miles an hour. They did this repeatedly to one of my friends who stays around here. So, one night, he actually sat in one of his trash cans, and when those kids came to grab the handles on his trash cans, he opened the trash car lid and said ‘May I help you'? I think they got projectile diarrhea and ran away."
From the time I was sixteen, I visited Mr. Glenn at his home at least twice a week. I found him to be a very interesting man who had plenty of stories to share with me. The first thing that I learned about him was that he was born in the 1920s, which was a bad time for African Americans in the United States. Mr. Glenn often cried while telling me that he was discriminated against. I remember Mr. Glenn telling me that him and many others were treated like animals than human beings. "We had to enter school through the back way, and we were not allowed to drink from certain water fountains or eat in or at certain restaurants. We were treated horribly because of our skin color. I think they called us every curse word in the English language", Mr. Glenn said.
Later in his life, when Mr. Glenn was seventy, his wife died in a horrible car accident, but he stayed strong. I remember him saying that he loved his wife and what happened to her was terrible, but he knew that she was in a better place; he said, "I see no reason to get upset about it, my wife is in heaven and I cannot wait to until I am there with her".
Two years before his death, Mr. Glenn shared some bad news with me. He told me that he had been diagnosed with cancer. After hearing this, my bottom lip started to shake, my jaw dropped in shock, and tears ran down my face. I can say that I was sad because I did not think he deserved that. However, Mr. Glenn thought positively; he said "I will not let having cancer get me down. I will enjoy the rest of my life. I will beat cancer". I just could not understand how he could stay positive when bad things were happening to him. I remember him saying, "I caused this. I should not have smoked all those cigarettes. This is my fault, and I will fight this. I can tell you that I will fight this to my last breath". And, he did.
Mr. Glenn was a great man. He had many obstacles to overcome in his life, and I believe that he overcame most of them. I love this man, and he was actually the only father figure in my life. Whenever I needed advice, help, or encouragement he was always there. I will never forget his last words that he said to me; he said, "David, remember to enjoy your life. Don't let anyone tell you that you cannot do something because you know you can. The sky is the limit, dream big." I am still impressed with how Mr. Glenn used humor to overcome most if not all of his obstacles. Sometimes, I still don't understand how he was so happy when everything bad was happening to him. From Mr. Glenn, I learned to never give up, to love everybody regardless of what they look like, and to keep fighting to make my dreams come true. Rest in peace Mr. Glenn.
