I was living in a shared house a few years ago and had the downstairs room. I'd left the french windows open as it was a balmy summer evening, and a fox wandered in. In my sleepy daze I thought it was someone entering the room and yelled out at the top of my voice. Not one of my four housemates came down to see if I was ok :-/ So I guess my point is don't feel bad about it people it's just the human condition.
