There's a group of us who meet up a couple of times a year, used to do a hobby together, friends of friends etc- quite a mixed group which has evolved a little over the years.
We meet up for a big boozy meal a couple of times a year as a large group.
Some of us go out in a smaller sub group much more frequently (old friends) - everyone knows that and is fine with that.
I'd arranged for the smaller group to go for dinner - bumped into one of the larger group who said, oh, when are we going out again? So I, without really thinking said - Oh, we're out on x date - why don't you come too?
But she then went and invited everyone in the larger group - thinking it was a large group event and I'd forgotten people.
I should have nipped it in the bud and didn't. There was the chance when I found out about the first extra person and - being nice and v busy that day just thought oh, well one more? But it went on.
It's completely changed from small cosy dinner to big do.
What I want to do is tell the extra 5 people that really sorry, I've cocked up - restaurant will only take original small number and I'll arrange a big do in a month or so.
Or do I just have to suck up my stupidity and accept I've bolloxed up the nice meal at lovely cosy restaurant and turned it into something entirely different that none of us wanted!
