On a family holiday with my in-laws which I find really difficult anyway. My SIL described someone she met by saying ‘she moaned so much, she was like you on steroids’. I pointed out that it was rude and my DH said the same and she just laughed. My DH wanted to speak to her after again on my behalf to say she was rude to me but I hate confrontation and wouldn’t want to cause an issue with his family. I’m really annoyed, especially as I try to be positive and happy with the in-laws so I think it’s unjusified. Am I being unreasonable to be upset?
