I'd say I personally want more information before determining who is the psycho. I have on more than one occasion seen a person claim that they have a psycho who is out to get them, only to discover that the person making the claim is the one who's psycho, not the person who's allegedly out to get them. Or, sometimes, both are psycho.
There's a situation like that where I work. One of the advisers HATES the head secretary. She will tell anyone who will listen about what an evil bitch the secretary is and so on and so forth. Ya well, observational evidence does not bear this out. In fact it shows the opposite is true, the adviser is the source of the issues and is the one who's being a jerk.
So not claiming that this lady's story is untrue, but I'm not willing to believe it without some more verification. Particularly in light of the other trivial issues like the hula-hoop thing. Often a sign of psycho behaviour is making a big deal out of little things.
