best friend in grade school 1958

David was a great friend. I knew him before he was in the service. We were friends from the 6th grade in 1958. If anyone would like to know more about David and those younger years, I would be happy to tell about that time period. I have some pictures, too. Because we were both new to this school and town in the fall of 1958, some kids in the class thought that we were brothers or twins maybe. I guess we looked that much alike. We were not. But in time we became brothers! His voice and words are still in my head.
