Friend told me on the day (around midday) that they couldn’t make my dinner party. It was a great night in the end but spent a fortune on wine and prep and so annoyed by the thoughtlessness. This isn’t the first time and they don’t ever miss any events organised by them, or which are easy to get to (eg not having to trek to someone’s house). I am fuming! Excuse was really flimsy. I don’t know what to say back
