3rd times the charm... yeah right.
Back door was open because its warm here. I was sitting on the chair.
I started hearing movement out side and felt uneasy, but I told myself it was nothing.
The feeling started to get worse and I realized it was the thing from outside again.
The dog walks in and looks at me, then walks off.
She went outside.
I stupidly looked at her as she went through the back door and saw the crouching see through, almost brown, figure turning around to follow her.
Why does this one strike me with so much fear...
