I should say that I don't dislike my MIL but it took me a long time to realise that she was on a completely different page from my Mum (who would fight like the devil for any of us, go without for us, and help anyone who she thought needed it). My MIL needs to always be the centre of attention and is validated by people running after her. I changed my expectations and, most of the time, I can roll with it. I figure I can shake my head and laugh about it to myself, or get stressed.
