My grandmother is in her late 80s and is generally really 'with it' for her age, however, she occasionally makes little mistakes when she recalls memories. If it was something important, like forgetting what no. bus she needed or something to do with medication, I would of course correct her. But when it's something unimportant like getting the year we went on holiday wrong, I'll just say nothing and let her carry on. My family feel they need to put her straight on everything. Today, she recalled a memory from when my bro was disappointed with something when he was 8. As it turns out, she wasn't even there. They spent a good 20 mins proving that she wasn't even there for this event. I was sat next to her and could feel her embarrassment. She became flustered and made more mistakes. AIBU in thinking they need to let these little things go and humour her? How do I tell them this? She's elderly and will make mistakes. Does she need to be pulled up on everything?
