Infidelity is somewhat common but I would say it’s not “normal” at all to openly discuss and laugh about it at dinner with a bunch of people that you haven’t seen for years.
Seriously- wtf is wrong with these people? That one person sounds especially horrible.
Also - don’t go to any more reunions. I’ve managed to avoid 40 years of that shit and I like to believe that I’m happier for it!
Goddamn …. That is a thing of horrific beauty. I saved it immediately.
