When 0ne person pushed into the queue ahead of me to buy her museum ticket, I let it pass. However, I was not prepared to let a second to take advantage of me, so I challenged the next one as she stepped forward.

I expected this elderly woman to apologise and move out of the way. Instead she spouted a vile speech about my selfishness. Apparently she was a former work colleague of mine who had never forgiven for me for stepping down from a role on April 1st one year. Since senior management had not found a replacement for me, she was lumbered with a pile of extra admin. The workload was so great that she was forced to cancel a foreign holiday with her sister, and missed out on a visit to a building with elaborate ‘iced’ ceilings.
