Psychotic Neighbor and Secondhand Smoke

My neighbor is psychotic and I mean that in the literal sense of the word.  I didn't notice it when I first met her last fall; a package for me was dropped off at her apartment and she seemed like a friendly person.  However, my views soon changed as the voices next door became, shall I say, creepy?  It then took another few months to realize that the sounds were not from a child, or another person, but that she was communicating with herself.  what the hell...(WOW I just heard her outside!  I went and looked out my window, and she was sitting on the table right outside my door just STARING at my place, talking with herself in a variety of voices.  Haven't felt cold chills like that in a while).  

Back to the story...I have counted and witnessed at least 3 personalities.  It is a rare occurrence when I see her since she does not leave her apartment so this day has been weird.  Earlier, she was leaving her apartment, saw me and jerked, so I tried to be friendly.  Lets just say the voice that responded was not the same as the other I met.  It caught me a little off guard.  

My main issue with this lady is her smoking in the apartment; due to some issues in my bathroom (a hole behind the light), the ventilation is connected with her place.  It has been incredibly frustrating to deal with, and in her state of mind, I do not feel like pissing any part of her off. 

The lesson I will be taking away from today is that I need to lock my door every night.
