I've planned a get together for a special occasion next week and just invited just my parents and in laws - we don't have a big garden and the food I'm doing is more knife and fork style rather than sandwiches/sausage rolls etc so with our household and them we are full.
Anyway it turns out my dm's best friend p/my godmother who we haven't seen for years is staying locally for a few days and she's told them it's fine for them to come (in fairness they haven't seen each other for years so I let that slide)
Then yesterday I found out that dm has been telling my siblings about my "party" and they're also expecting to come, so it's just all getting out of hand. If I tell them they can't come I'll be the bad guy! I can't even change the food as I've bought all the ingredients.
