You picked up the phone and everyone came over, that’s cool. What number did you call? Was this a public service of some sort?

I'm not sure if you're joking, but I think it was implied that OP called the people.

Right. I think the underlying question is, how do you get to know these people in the first place?

Isn't this the whole point of the discussion? How do you initially get to know people?

Yes this is the meta point I was working at. OK any of us can call our friends to come over, how does one make the friends in the first place!
