You think you have ghosts!!

I was working in the office on the computer this morning and I heard this big pop and then the sound of broken glass. I went to check on Hayden and Katie who were still asleep and then I began my search. I finally found the source of the problem, although I have no idea why it would happen. When I went in, there was a big hole in my shower door and the glass was just shattered. It continued to crackel and break while still in the garbage. I knocked the majority of it out and cleaned up the mess--now I need to look in to a replacement.
