I heard something scraping on my window last night. I got up to investigate.
Scary!!! What was it?  Were you terrified or just curious?
When I got to the window I didn't see anything. I opened it up and peered outside. That is when I saw a slender shadow slinking off. I was so scared.
I would be too!  Did you try to see if you could see someone from another window or just run back to bed?  I'm glad you're ok!
