Am I suffering a sense of humour failure or is it utterly dispiriting that our local shopping centre (Centre Court in Wimbledon) is celebrating Mother's Day by holding a competition which includes these categories: Baking Mum, Sporty Mum, Beautiful Mum, Fashionable Mum, Glamorous Mum and Stressed Mum, and that the local Mumsnet site is involved and supporting this cliched, unimaginative, sexist rubbish.
