Collision with a lorry yesterday on his bike. Died at the scene. He was 50 and leaves three small children and his wife. I sat next to him for seven years. We weren't "friends" in that our relationship was siloed in that mental space reserved for work people. But I liked and respected him. And spoke with him a lot. I feel really sad today. But weirdly feel wrong to grieve given that he was someone who kept his personal life away from work, much more so than me. Posting to express the feelings.
