There was a wedding of a close family member to which we were not invited. My sister knew I was upset about this because I told her, I also told her I didn't want to know lots of details about it or see other peoples photos because it was too upsetting. A few days later she changed her profile picture to her and all my family at this wedding which I found difficult to see but it is her business. Then she asked me why I hadn't 'liked' her picture knowing that would mean the bride would see i had 'liked' it. I said I didn't want to do that and get involved and now she is in a strop with me because I didn't 'like' her picture. I think it's obvious I wouldn't want to and so far I have adopted a no comment stance about the whole thing and prefer to keep it that way. AIBU to think she's shit stirring a bit?
