[This sequence of concepts is less closely approximatable as English sentences, but it goes something like:]
:There are many places, and mine is one of them, where we think of the home as a sanctuary. The outside world has its filth and dangers (as I am all too aware, having been recently reminded), but the home protects its people. One doesn't take the precautions at home that one would take elsewhere, amongst things that strangers have touched and air that strangers have breathed and even a tree in the forest that a deer may have pooped on.
The home is kept apart, and one mustn't track the impurities of the world at large into it. So that you can move freely, and be at peace, and have things that belong to you and your kin and are not shared with the parasites.
(To not have to wonder, is this safe? Is this clean? Or is it the thing that will cause me to spend days burning with fever and barely able to tell reality from dream? Or crushed beneath the weight of pure, elemental misery? Or fragile with nausea, and deprived even of the ability to lie down and do nothing? (Or waking up dead one morning?))
So in our entryway, there are jackets and boots, yes, but also a place to keep your bag with the things that are yours but which belong to the outside, and a place to keep new things that *will* be brought into the household but do not *yet* belong, and a handwashing sink with purified water and soap, and a set of...not *fresh* clothes necessarily, it would be wasteful to launder your clothes every time you left the home, but *separate* clothes. (Some cultures put showering areas or places to clean your feet in the entryway, but we normally don't. There are probably other variations I'm less familiar with.)
...some of this was probably rude, and I am sorry. I don't mean to accuse you of foolishness. And I have a feeling that soap is expensive here.
But it...:
(He does not say that "it will take some getting used to", because he's not sure that getting used to it is possible or even desirable.)
:...well, it's very disconcerting for me. I'm sorry for the outburst.:
(He has not known sanctuary in six days, and it is starting to sink in emotionally that maybe he never will again.)
(He's never going to know whether or not he infected anyone in his unwitting violation of the household sanctuary, before he knew he was unclean. Maybe they just hadn't finished incubating yet.)
