Liz, years ago we had some really nasty neighbors (Banditos hang arounds). Before I realised who they were, I had complained to the wife about her always leaving bags of garbage on the staircase. From then on, it was war! The guy was rather nasty and threatening towards us, so we half expected our door would be kicked in sooner or later. At a point we thought of getting something to defend ourselves, so I called my cousin's wife, who was a cop at the time, to get some advice. The plan was to get a pepper spray from friends in USA, but she told me that that was illegal to use in Denmark, but suggested we keep a hair spray ready by the door. Well, luckily it never got to the point where we had to use it. They were kicked out soon after.

Hope everything falls into place, and you can relax again.
