This story takes place in my hometown of Sandy,OR.
I had just started dating my now fiance, Matt and was living with my parents, as I was still in high school. My parents would work during the day, so the house was empty. On a particularly cold day, we decided that we should go to my house to hang out, because I had the key and no one was there. It was a pretty good plan, and we hung out for a while. After a few hours of laughing and watching TV downstairs, we heard heavy footsteps upstairs-usually a sign my stepdad was home. As we prepared to leave, I went upstairs to check if anyone was home-there was no one up there. Shrugging it off, I went back downstairs and told Matt we could still hang. We returned to our show and heard the footsteps again-this time; we were a little creeped and thought it might be a good idea if we left.
We locked up and left as we were walking down the street on the side of my house though I got a phone call from an unknown number. Thinking it could be one of my parents' work numbers, which usually show up as unknown or restricted, I answered it-I got nothing but static. As I clicked my phone shut, Matt's went off-also an unknown caller, also static. Looking at each other confused we tried to figure it out. We hadn't been dating long, so there was no one that had BOTH of ours numbers. We were puzzled, but kept walking.
As we climbed the steep hill that faces my house's back porch, that is visible from the top of the hill, I looked back (I don't know why though, I just felt I had to). To my astonishment I saw a large black figure standing on my porch! Now, my stepfather is African American and rather large and muscular, but he wasn't home. I turned to say something to Matt but did a double take-the figure was gone, and I could see that the sliding glass door was open. Matt's explanation was that it was my stepdad whom we hadn't seen come home, but he came home late that night, and when asked he told me he hadn't returned home before then... Plausible, since his work is a pretty good drive from our house.
Needless to say, we never stayed at my house alone again.
