I've got a big birthday coming up and am having a girls night out on Saturday. I was with a friend in town and (encouraged by her) bought some ridiculously marvellous shoes to wear. Yesterday she tells me she liked them so much she's bought herself a pair and is going to wear them on Sat. AIBU to be a bit cross. They're very unusual shoes so we will look ridiculous if we both turn up in them so now I feel I can't wear them.
