My parents are having a big celebration lunch later this month. It's for their anniversary and it's a big occasion, there are about 80 guests attending, all family friends and extended family. I know they have put a lot of money in it, and I was really looking forward to it.
My parents said myself and my siblings could all invite friends, and both myself and my sister have invited old childhood friends, ones which our parents know- we were under the impression as it was a big family occasion they would like to see friends which they have known for years.
Now my 16 year old brother is taking his new "girlfriend". (I use the term loosely as he says they aren't officially dating, but they might eventually) None of our family have met her. This will be the first time any of us meet her, with our entire extended family and family friends.
AIBU to not want her to attend? I wouldn't mind if she was someone who I knew or my parents had met but she is a complete stranger. She also isn't my brother's girlfriend really- I wouldn't invite someone I was seeing for a matter of weeks to a wedding or similar event.
