I'm having a christening party for ds2 soon, which will be a big party for family and friends. Its taking place at my parents house, and I know they are both really looking forward to it - my mum's had an awful year with treatment for a life threatening disease and she loves seeing her grandchildren.
My sister has just said that she won't be coming, because her dh has a company day out and she would rather spend the day with him. I'm pretty hurt and upset by this - I can accept that BIL can't come as he is a company director, but I really feel slighted by the lack of care my sister has shown to both me and my family and also, I feel, our parents. Also, the company day out is a mere couple of miles from my parents' place and I think it would be quite possible to spend a bit of time at both (I have suggested this as a compromise).
Anyway I have made my feelings clear to sister(!) and vice versa, but now I feel really awful about the whole party - I can't think about it without getting angry and upset. I really don't want this to spoil it, and I also don't want it to sour my relationship with my sister, but at the same time right now I'm not feeling very forgiving.
Any advice about how to get some perspective and rise above this??
