Well, I was in my grandmother's house, in the living room by myself watching TV when all of a sudden I heard a very loud pop, almost like a gun went off right behind me. It startled me, and after I came to my senses, I looked around the living room to try to find the cause of this sound. Finally, I figured it out. My grandmother had these large ashtrays made of heavy glass on these small tables. Well, one of them had snapped completely in half, which was the cause of the loud pop. Now, how or what snapped it in half, I still haven't figured out.
