But this seems to claim it solves some practical problem with parties. I don’t know what that problems.

I understood that. I’m asking about the problem with parties that this helps people fix.

That would be the ideal for meeting new people, would it not?

I’ve read the whole thing and I feel like there’s something that’s just assumed that everyone understands.

What exactly is the problem? Why do we care how many people know each other or don’t? I’m so confused.

I get it. If I was looking at that seating chart, I’d be thinking:
“Screw it. If I have to sit in the front, I’m going to sit in The front.”
