DS is throwing a party in a few weeks to celebrate getting a new job. this isn't a particularly massive achievement, it's not something she'd been working towards. It's just a standard job thst pays a bit more than her last company. It's a BYOB and everyone is required to dress up in a certain theme. Also no children are allowed so I'd have to get a babysitter. Earlier this year she threw a 'Pick me up party' to help cheer herself up (she suffers from stress and depression and had just been signed off from work). Which in essence is a nice idea but we were all expected to dress up, BYOB and bring something along to cheer DS up I.e a gift. I wouldn't mind but the price of a costume, alcohol, babysitter and a gift adds up pretty quickly. And I'm sure there be another excuse for a party before Christmas.
AIBU not to go even though it's going to cause uproar and I'll be accused of not supporting my DS? I'm not a party person at all, but I sucked it up for the last party, do I need to suck it up again?
