I live in a downstairs suite in a house - it was orginally designed a single family unit and not meant to be an apartment. The upstairs neighbors can hear EVERYTHING that goes on downstairs, no matter how quiet one is. My neighbor has to go to bed early every night so she can get up early to go to work. I am quiet after 9PM when she's in bed (despite the law saying 11PM is quiet time). But I have to get up and pee sometimes or open a window for fresh air --- she hears it and gets very upset.
It's nearly impossible to talk to her, because unless I agree to her demand for total silence - (often during the day as well) - she resorts to name-calling and insults.
She rents the upstairs suite and I rent the downstairs. The landlord is away for an extended period of time and can't be reached.
