Nothing wrong with the n-word, Sen, if the context is understood. Which means 'carefully explained & carefully listened to'. These days, there seem few that can do either, let alone both. It isn't a word I'd use (except to explain why it shouldn't be used), but Guy Gibson VC, of Dambusters fame, had a dog called Nigger. I doubt he meant anything by it.

There are only two words in English I'd call 'beyond the pale'. The other is the c-word, despite its honourable antecedents (the same 'cun' as in 'cunning' & 'cyning', the A/S root of 'king' & all the Germanic language variants thereof). You can get away with pretty much anything else, but the c & the n... Use 'em very sparingly & very carefully! ;-)
