I really don’t know if I’m being unreasonable or not. My sister and I had a falling out quite a few years back and haven’t spoken since. I’m okay with that and happy to live and let live, I wish her well. Since we became estranged our Mother was diagnosed with dementia. She lived with me for a several years and three years ago moved into residential care. I visit her most days. She is physically great but mentally deteriorating. My sister also visits her. Mutual friends/family often screenshot photographs of my sister and our Mother that my sister has posted on social media and it really, really upsets me. She recently brought people to the nursing home to celebrate our Mothers birthday and photographs were posted. I feel these photos are not about our Mother - she doesn’t recognise anybody anymore or know what a camera is etc. She doesn’t understand and she just looks totally confused or blank. I have Power of Attorney for our her and I want to protect her dignity. AIBU to ask that photographs of her are not posted on social media?
