I recently moved in to a new (to me) house and am utterly confused by some strange strings that seem to have been put up by the last owner. I will be removing them but since I can't imagine any reason for them being there I'm starting to wonder if I've missed something and pulling them down will lead to disaster (sort of joking)?
They seem to be standard white string attached very close to the ceiling around 3 walls of the living room, attached to hooks that seem to have been screwed in to the ceiling for this purpose. There is also a (pretty old and not working) alarm system and I initially wondered if they were something to do with that, but they don't seem to be attached to it and do seem to just be string.
At first I assumed they must have been for Xmas cards/decorations or something but I can't see how that would work as they are so close to the ceiling.
Photo attached. Wise people- do you have any idea what these are?
