Okay, so make that a handful of college students sharing a rented house (on a single lease, not separate units): they're all hugely into video games and want to be professional streamers one day, and they all have very different schedules, so for most of most days at least one of them at a time is streaming in 4K to a Twitch channel.

I mean he’s paying for two lines. So make it two four person households.
