Quite a few months back, my professor from University of Nebraska went to work with one of his collaborators at University of Texas at Arlington is an hour or so away from where we live. It was great to have him and it felt like old times. I am really going to miss having an excuse to talk to him every week. I started helping him with his undergraduate research shortly after he started school at North Carolina State University. The research was successful and extended into his Ph.D. research. We had such a good time with it, we talked about how I might be able to continue to help him with it as a retirement project. I never expected to have the opportunity to do that in the way it worked out. I am grateful for the whole enterprise with my lifelong friend.
