This would have to be one of the scariest reads I have ever had. It's ten pages long, but I have goosebumps all over, not sure how I am going to sleep tonight and not sure how I am going to feel next Saturday, because there are several "Squeezes" I am going into that are very similar to this story.
Read it if you dare. Read it all.
