When I was a teen the young chickie across the road asked me if I would like to help her baby sit that evening at her sisters house. We were fooling about on the couch - I'll spare you the details but were were quite involved. Then there was a huge door slam in the middle of the house. We thought it was her very pissed off sister back home early so clothes back on etc but the was no one there. and the doors were locked. And the kids were asleep up the other end of the house. Being teens we were back into it, and again a huge wham as the internal door slammed. There were no draughts, windows closed and I had left the offending door closed. This happened a couple more times then the roll down blind next to us shot up. That was it. It was like a b grade horror but happening around us. I said to Robyn that I was out of ther and for her to bring the kids and come with me but she wanted to stay. I still feel bad about leaving
but it was pretty scary. When I got home my phone was ringing and it was petrified Robyn speaking. As we talked on the phone until her sister got home the door slammed another 8 or 10 times. I didn't find out what happened after that as we never spoke again
