my mum and dad have their 50th wedding next month and of course I want to have a celebration for them. However, my suggestion of going out for a meal has been rejected by my sister in favour of lunch at her house. Now, this shouldn't be a problem, however I always feel that myself and my family are unwelcome at her house. On the rare occasions I speak to her on the phone it's like a business conversation, there's no warmth, she never asks about my children, she barely speaks to my husband or children when meet, and there are often veiled criticisms to my face and stronger ones behind my back. I've lived with this for a long time, rising above it, always asking about her children, ringing to congratulate when good things happen for them etc. However, I finally feel that I can't do it anymore, or subject my family to it. Problem is I'll have to be honest with my parents, about why I don't want to go, which will upset them even though they know she can be awkward, and I'll also have to find an excuse. Should I grin and bear it for the sake of my parents or be honest with them and have a separate celebration?
