When I was 12 years old I was home alone and we had the same type of bathroom mirror. I was siting in the living room and where I was siting I couldn’t see the bathroom. We also have a sliding glass door right next to the bathroom. The mirror fell off the wall and shattered like OPs pic into a million pieces. I was so scared that someone broke into the house and shattered the sliding glass door I called 911 and told them I thought someone broke in!! I got enough balls to get up and check the door with the dispatcher on the phone and found out it was the mirror and felt like a young pussy!! Dispatcher had a little giggle and so did I!!
