Going to the cinema tonight with a friend. I'm driving us both and have messaged this morning about picking her up. She's replied saying that Sarah is also now coming. There was no mention of Sarah coming before and I can't stand her. Her child has always had a hold over mine, leads him astray, teaches him swear words, tells him he's a best friend then an enemy. I don't want *Sarah coming on our night out and I def don't want her in my car. She's so patronising and generally a person I'll say hi in passing to but always try and stay away from. Very annoyed. Original friend I don't see that often and obvs doesn't know any of my issues with Sarah. What can I do??!! AIBU to not want her in my car and invading my night out.
