My hs reunion involved the organizer invited more of the class only when they realized they needed more people to help pay for the venue, myself included. This was done less than a week before the event.
Actually ended up reconnecting with some people that received the later invite in shared disgust so that’s a nice thing. But it also made me realize how little I wanted to interact with any of the main group.
That’s my initial thought as well. The weird thing though is he’s already rich, he could bugger off into obscurity and live a life of luxury, but it seems like he just craves attention.
