It was pitch black inside. I was a little far away, so I couldn't make everything out, but I remember that. Since it was so dark inside, I could see the thing holding aside the curtain clear as day. The person inside was white as a sheet. Not pale, just pure white, can you believe that? The second it saw me it closed the curtain, and that was that. I keep walking by to see if it'll do it again, but no luck.
