When you have a densely connected network like that, not only are the friendships more rewarding, but everyone else also becomes more important to each other for mutual support, like Metcalfe’s Law. A densely layered quilt is much stronger than a seam sewn by a single string.

Not everyone who joined a bowling league (when people did such things) loved bowling. Many loved being with other people first and bowling came second or not at all. Being together is what mattered. The venue did not.
