Off Topic: One Less Bright Light

My weekend routine changed a few months ago. When I took the kids from one place to another, we used to cross paths with a young man, a graduate student. We would stop and talk for a minute or two when we ran into him. Since I hadn't seen him in a while I asked someone who worked with him how he was. Not long ago he killed himself. As all too often happens no one had any idea he was troubled. You just never know. A lot of people, my family included, will miss him.
