Discussion:
Anyway, I gathered all of my courage and crept slowly to my window. I held my finger out and raised one of the blinds. I had my eyes closed doing this. I opened my eyes and looked out. My eyes met another pair of eyes. What I saw will haunt me for all 
of my life. It was about 15 feet away from my window. It was a naked dark grey creature about 3 to 4 feet tall.
