Name changed as this could be outing. Last year, we went to my mum's to watch the coronation. At the very moment that the crown was being lowered onto the kings head, my mum asked me to sit in front of the TV so she could take a photo of me next to the TV image of the king. I said "no, I'd like to watch this bit". This made my mum unhappy and she sulked for the rest of the day. As it happens I had already agreed to have such a photo taken earlier in the ceremony, even though I was still in my pjs. A year later she brings this incident up in arguments as an example of me being difficult. In her view, it was selfish and rude of me to say no to a simple request and that anyone else would have posed without argument. Was I unreasonable?
