I had a rather unnerving experience this past winter. Being unable to sleep at 4am, I went outside for a cigarette (I live in an apartment complex). Suddenly, out of the darkness, appeared a tall bulky figure dressed in black. They were coming straight at me!
Well, I'm in a wheelchair, so can't move too quickly. I just sat looking at them, trying to figure out whether I could reach the broom at the corner of the porch.
Well, that would have been an option. The person came right up to my porch and said "Good morning. Can't sleep either?" It was my friend and neighbor walking her dog and I didn't recognize her with all her winter gear on. Scared the daylights out of me!
