I agree with cat64. People should remember that 'walls have ears' and should at least look around to see who can hear. There's an old adage, "Never attribute to malice that which can be adequately explained by stupidity" but I often wonder whether that is true.
Everyone is entitled to their opinions. However, good manners and social graces decree that you don't say things that may hurt someone's feelings - especially a young child - and you should take all the necessary steps to avoid such rudeness and meanness.
Nonetheless, in my case, such bad manners and rudeness goes against my family's values, which is why in the last 5 years, I've changed GP, health visitor and, in my daughter's case, nursery. The nursery bit was a shame, because dd liked the other children but I thought to myself, "do I want my child to be cared for, and taught by someone who is rude, openly prejudicial and judgemental and so indiscrete? The answer is no.
My daughter currently attends the nursery department at an independent prep school. They were the only ones who seem to share my values and strangely enough, do not equate fat person = poor person to be shat on, despite that sector?s reputation for being exclusive. It's a headmaster and wife team, religious but not too overtly. They are polite, tactful and helpful. A shame not more people are like them, the world would be a much better place.
My dd still remembers but thanks to her new nursery, she now realises that it was that uncouth woman who is in the wrong. Dd is learning that being nice, polite, inclusive and sensitive, especially to people who look ?different? is just as important as learning to share and take turns. Something that I doubt she would have learnt at her other nursery.
