My mum-in-law, at 89, is as bad. She says she's not racist, but it's funny how, if there's ever a carer at her home whom she doesn't trust, they're usually black or asian. Funnily enough, the Spanish and French staff are 'lovely' according to her.
I'm terrible. MiL is right snob, so when she's trying to disguise her racism, she says things like, "she's a coloured girl", and so I say, "Really? What colour? Green, Purple, what?" Usually shuts her up.
Unfortunately, it's not just the older generation. I could have cheerfully punched my sister the other week, and I doubt my hubby would have stopped me, either. She's 52 and has grown up in the same, very multi-cultural city (Leicester) as me. So tell me why she complained when she got home from a trip to Sainsburys because there was, quote (and I'm really very sorry, folks) "a family of nig-nogs at the checkout, holding everything up".
I mean, why? She's supposed to be educated, for crying out loud. Works in customer service for a very well-known chain of car dealerships. I wonder, does she talk about her Asian customers that way?
Your sister is lucky to have you, Petes Dragon. Give her lots of support, tell her she's got some long-distance support here, and ignore the family. If they don't come round, then I'm sorry, but they don't matter.
