Dave was my Best Friend at John Glenn High School (1966). We also attended Spring Arbor College together for a year. We spent so much time being goofy, silly and just plain fun that we discovered that we really didn't date much as silliness took prescidence. You always knew when we were around as you would hear strange sounds from us such as, "MOWERY!" and "FRIEBEL!" That was to announce a new round of silliness or to provide a warning to those who didn't appreciate our silliness. In fact, as I retired a few years ago I've been thinking about starting a business known as the "Technology of Foolishness."
We never intended to be malicious and I'm sure that we would be embarrassed to know that we hurt someone. So, if we did, we apologize.
As an educator, I am so impressed with the number of Dave's former students who have contributed to this obituary. Good for you, Dave!
