My bathroom sink - the pedestal beneath it, has moved about four to five inches back, and there is a large chip near the top, like a thin slice which was on the floor. I share the house with my adult son who has ASD and he is equally mystified. It looks as though something hit it or someone kicked it. I am driving myself mad wondering how the hell it happened and I can only come up with someone got into the house while we were out or asleep but nothing else is disturbed or missing. I literally have no idea how this could have happened. I would be very grateful if anyone could shed a light on this.
