I have always been friendly whenever I see the lady downstairs.She is self professed to be bi-polar among many other psychological and physical problems.Several time since I moved in upstairs over her 4 yrs. ago,she has fits of unexplained harassing behaviors.She repeatedly tapes unfriendly contemptible notes with accusations of how much I have in my apt. She is delusional and thinks I listen in to hear whats happening in her apt.through her walls.She puts a radio playing loud music outside her apt.,in the hallway ,where me and my company have to hear it day and night,24hours a day.I have had feces left on my stairs and packages stolen since I moved in. I'm 62,and never in all the homes I've owned or lived in ,have I had such unbelievable behavior from any neighbor or tenant.Her latest issue is, that two of her ceilings in her apt have cracks and she believes it's my belongings in my at causing it.I don't even own a sofa.I'm handicapped and made my living room int a bedroom and the other are used for storage of clothing .The house is 90 plus years old.The landlord doesn't have any solutions.I'm tired of her using her Section 8 housing card that she plays along with her threats to call the state about me,over everything . I'm a great tenant and my landlord will agree.I knoe I'm not guilty of anything herein accused of,but,I'm tired of walking on eggshells with this deranged individual,and she's starting to scare me.
