My DM has a big birthday soon, we are supposed to be going out for a family meal. I think the children should pay for this which will include extended family, around 20 people altogether. One sibling thinks we shouldn't, only for DM, the others should pay their own. Feel embarrassed as DM wouldn't be expected to pay towards a meal if she was invited out by her extended family. Also know this sibling has the money, also DM has helped this sibling out in many ways including childcare for years. Other siblings are useless and don't want to get involved. Getting sick of the lot of them and feel like telling them to get stuffed!
