Deepest condolences on your loss. I didn’t work that frequently with Stephen but I always looked forward to the opportunity. He was always friendly and approachable, providing sound advice and never left me feeling that I had wasted his time regardless of how trivial I might have thought the question was. The response ‘perhaps we need to decide which verb should be used throughout’ remains a particular favourite alongside discussing whether the absence of a comma substantively changed the scope of who needed to complete aviation security background checks (thankfully it didn’t but we added it anyway). He will be greatly missed.
