This is my least favourite thing. I thought I was just being miserable, I didn't realise that it's normal to get annoyed.
I too have a friend that does this. Most recently I invited her to a nineties night in a local city, and 45 minutes before I was due to pick her up, she texted "I've told x we are going to city, she wants to come, you don't mind do you?"
And I didn't, really, but then x was a miserable bitch who wanted to go to funky rnb clubs. I don't like funky r n b clubs, I like the spice girls and dancing round my hand bag in a safe space where I don't feel old, fat and past it. And for fucksake I was driving, so was sober.
Anyway we went to the nineties night but not before a passive aggressive tantrum at 10pm in which I offered to drive her home "right now, really I would NOT mind". She sulked with half a lager until 1 am when I called it quits and took us home.
And really, although she was a miserable bitch and wrecked my night out, I'm still cross with my friend for bringing her.
