Rebekah heard a strange sound one morning in her sleep, only for her to wake up and discover the sound was real. It was the sound of glass cracking, and she discovered that it was coming from her bathroom. A pane of glass in her shower was cracking — but not breaking.
Nobody had touched it and nothing had been thrown at it. The glass had an imperfection that eventually caused it to crack on its own. So what do you do in a situation like that? Obviously, you grab a NERF gun and finish the job!
