I am thinking that it may be worth while paying for my parents to have a romantic dinner somewhere nice just the two of them on their anniversay and then hold an informal family gathering at the weekend. I sometimes think I am so close to the mess I can't think rationally.
Sounds like you have a good idea here. It's hard to think rationally when you are dealing with irrational people. Talk with your parents say you want to celebrate their marrage with family and freinds and want to include everyone in the planning but are afraid some will make things difficult. See if they have any sujestions on how to proceeded Since this is their day.
