She has looked after the place forever. People come and go - so many of them over the years - but she is a constant - always on her rounds. Some of the doorways that she walks through were bricked up a long time ago and, in the open plan kitchens, she still turns to follow the line of a wall that was removed forty years ago.
We are used to her and, apart from occasionally pausing for a heartbeat to allow her to pass, we pay her no heed.
