>>17078831This social norm can be implemented if you can force your visiting friends to wear sleepers which you have to provide, some did it in the past but isn't always doable for why would you slip your feet into something which isn't yours?
Also, any pets around? Because that'll be another layer of nonsense, unless you don't make them wear socks indoor too.
> just stay with your socks broThat's even grosser, what if they have bad higiene? What if they're sweaty after a walk?
Not saying it isn't a concern to bring crap from the outside, but you can't avoid that completely IMHO.
The best solution to this is not to receive anyone nor go to ither people's houses, ever; misantrophy solves all of these issues.
