Book group meeting last week, and one group member said she couldn't remember the name of a book she'd thought of choosing, but it was about two coloured girls and their halfcaste children. I said "Anne, you can't use those words" and she said "Why not, what words are you saying I should use?" I said "Black and mixed race" whereupon she said " Well, a mix of black and white is grey, should I say that?" and grinned at me uneasily. I turned away and started talking to someone else. Another member later said I had probably upset her, and maybe should have ignored her comments. What do you think? She was being racist, wasn't she? But I'd never heard her say anything like that in all the years I've known her.
