Thanks, puzzled. It makes a difference that someone understands what I mean. My DHs friend and colleague is one of those black men who uses the N word quite liberally. Mainly as it visibly disconcerts the office staff! So DH is often in a place where it is used.
This is what led to his 'oops'. He was talking to work mates and started to use a phrase I think was mentioned earlier (working like a N) this man uses regularly and realised it wouldn't be acceptable from the mouth of a middle aged white man! But he had never actually considered the phrase before and, maybe like Clarkson and the nursery rhyme, the childhood familiarity almost over rode his common sense.
ohmymimi I don't believe that is possible that you have never used it. You say never as a perjorative, that's a nice little caveat and is the predicament I am referring to. Such language was utterly endemic when you were growing up. From Alf Garnett and The Play for Today, political speeches, daily language that your elders would have used and your childhood peer group would have heard and probably used. It would have been 'normal' then.
So to say you have never have said or thought as a pejorative it is disingenuous but does describe the problem my DH encountered.
Again, that he has discussed his feelings and embarrassment is, as far as I can see, a reassuring thing. He didn't hide it, convince himself he was right, bluster or pretend it didn't happen. He started a discussion about it. With me, with his work mates and with his friend. They all laughed and agreed that, sometimes, your childhood, reading Biggles, watching Alf Garnett, listening to Grand dad, can sometime strip you up. None of them thought his was racist or disgusting. They (a mixed race group of about 15 men in their 50s) had a long rainy day, stuck in a cabin on a work site in Wales, conversation about it.
I still don't see why that makes him, or any of them, a twat!
