One thing that I have learned about crazy old ladies is that typically, (and I would hate to make a sweeping generalization here) the longer their goatee, the more they are out of their mind. The stench of urine they emit also holds some type of bearing on mental stability, with the more pungent odor signifying less ability to function within the social constructs of civilization.
The building that I am currently living in is an exact replica of the hotel in the movie The Shining, starring Jack Nicholson. While that in and of itself doesn’t raise an inherent sense of fear, the thought of that combined with the thought of a 55 year old schizophrenic woman who drags around a laundry cart filled with heels of bread, walks with a limp and plays on the elevator until 3 in the morning, does.
