You said goodbye first, which is awesome!

I will let randoms know that a friend requested to join up and thank them for the dives and then wait about 10 seconds before booting them in case they were in a huy menu or something. Generally I get a thanks back and they leave before I'm ready to boot them. Even got a couple friends invites after!

Maybe the community will spoil in the future, but for now people are pretty chill with groups disbanding after dives for any reason.
