I will tell you a true story, with the name changed.
Over thirty years ago now, in the staff common room, with people sat around drinking tea and coffee and eating sandwiches a senior lecturer, rather older than me, told me, quite loudly, that he had advised a student to come to ask me something, and added that he had said "he's the very tall gentleman". So, calmly and politely I said that I thought that he should not make comments about my height to a student. The man proclaimed that it was perfectly reasonable to do that. A Research Assistant mush younger than me commented. "I agree with (Mr Smith) it is perfectly fine to describe a member of staff's appearance to a student." Oh dear, I thought. But then he added "If I was sending a student to see (Mr Smith) I would say "Go and see Mr Smith, he's a little fat man with a red face,"
Well, the roomful of people erupted in laughter at this, for quite a while. With three exceptions. Me, who kept a straight face, Mr Smith who gave a noticeably forced embarassed smile and a senior lecturer who had spontaneously laughed but alas was in the process of drinking a cup of tea at the time and he was now with some embarassment trying to mop up tea from the coffee table after it had come back out of his mouth.
