Humans are social creatures. Even the solitary ones. - MolluscsAndMonsters
Humans like me have a saying: No man is an island. Or words to that effect. And... they're right. Even antisocial assholes like me need to brush shoulders with other cogniscents now and again.
But that's why I have the mail run to the cul-de-sac strings. You get wormhole chains like those. Places where it's ten or more jumps to any nexus, anywhere, and the places along the trip are the places that people come from rather than go to. And the people who choose to live there? They're always glad to see people like me.
Just like the ancient Pony Express or the Wells Fargo Wagon of old, these are folks that are more isolated from Galactic Society than I am. They get entertainments in season binges. Updates by the year if they're lucky. Everything cool is expensive, and they often have their own fashion, and seek news of the latest thing that, by the time I reach the end of the cul-de-sac, is months out of date.
