An invitation is not a summons. I wouldn't agree with lying for DD, but advising her that if she doesn't want to go, she should just tell them it doesn't work for her. She doesn't owe them an explanation.
One thing I think is being overlooked here is that I believe it's DD's birthday. Why should she have to give up HER special day for something she won't enjoy? Her birthday is about her. I recognize that SFIL has a birthday too, but I doubt it would be entirely ruined just because ONE person didn't show up.
My husband is high-functioning autistic. We don't attend most large extended family events, mainly because I know he won't enjoy it and it will be too much for him.
Ethical question - how do you feel about second chance??
