Yep, my own experience with doing the Irish exit had always been either at a friend's place or a bar, when everyone is trashed, especially me, and I get the urge to go find a club to dance or whatever other shenanigans my lizard brain thought I should do. I'm getting old though, been a while since it happened.
I'm Indian, and pretty much anybody who comes over is Indian too, and almost every time we have someone over its like 30 minutes from first goodbye to actually leaving. I love it, but it can get annoying.
Yea, first thing I thought was "you mean there are savages in the Midwest that don't take 2 hours to say goodbye to everyone they know at big gatherings?"
Right up until they do, and spend 10 minutes checking to make sure you weren't hurt or otherwise injured at their party. This is fine for big public things, but is very much a dick move for smaller groups.
