we had a big party yesterday and at dds request I invited some of her friends from school with their familes
one mum phoned and asked if it was ok to bring her sister and her 3 children as well as her, her partner and their 3 children making them a group of 9 in total. no problem the more the merrier
not one of them turned up. no text no phone call nothing.. I sent a text this morning and just got a message back saying "oh sorry didn't really feel like it"
aibu to think this is both rude and inconsiderate ?
