Perhaps I should add that I'm not the most assertive of people and I don't find it easy to stand up for myself. On this occasion I tried to do so, in a calm and non-accusatory way. This attempt was rebuffed, in front of colleagues [thank God] and in a manner so contemptuous and peremptory that I was left reeling. Please don't say that it's just one of those things. I feel deeply insulted.
