I've really never understood these "X number makes an event" kind of situations.
So what would happen if three XYZ members happened to show up at a the same party and none of them knew any other XYZ's were going to be there? And the party isn't being thrown by any XYZ member?
Does legal age or if the party is at a bar come into play?
What would happen if an XYZ from *another* chapter - say an alum - happened to come to a party where there were two active XYZ's from yet another chapter? Do the three of them an event make?
What about three separate biological brothers (or a say a Dad and his two sons) who are all members of XYZ and happen to have or attend a party? That just might rule out quite a few family holiday events.
