The Peroni Glass Incident:
My supernatural roommate first introduced itself with the shattering of a Peroni beer glass (picture below). I 'borrowed' this glass from my local pub and it was my favorite beer glass. In the mornings I would rinse it under the tap and and place it rim-down on a paper towel. The tap water wasn't too hot or too cold, and on the day it was resting on the towel for several hours before I heard the sound of glass shattering.
When I went into the kitchen, I found that the rim of the glass was perfectly intact on the towel. But the rest of the glass had exploded like a glass hand grenade. Notice the thick base of the glass, the base had turned into glass nuggets strewn all around. I wish I had taken a picture. At first I thought that something rolled out of the cupboard above and fell on it. So I searched and didn't find anything. I thought it was just a strange thing. I went online and found some stories about glass spontaneously breaking, but the the breakage was usually blamed on rapid heat transfer or imperfections in antique glass. But whatever, strange things happen. And in isolation this event would have been forgotten. But this was the day that marked the beginning of the strange happenings that would follow for the next few weeks.
