We were on our way for a walk along the Thames when a phone call brought the terrible news of an ex-colleague’s death. She had taken over my role when I retired. She wasn’t sure whether she was up to it and I also had my doubts – it was a sometimes technical role. But she accepted the position, and despite requiring my help every once in a while for the first couple of years – I don’t think she ever really mastered database queries – she was a success in the post. She was always bubbly and cheerful, which makes her taking her life all the more shocking and hard to comprehend. Things change, but I wish I could turn back the clock.
