Fixing our front door

[mtbc]

Our building has communal areas, our flat's front door is within. Recently, the locks stopped working well, as if the door suddenly didn't quite fit any more. I peered at the door in some puzzlement, opening and closing it, trying to understand what had changed, if a hinge was failing or whatever. It was R. who figured it out and fixed it: a small stone had somehow lodged under the thin piece of wood running along the floor under the door, pushing that wood up a little.
