yah right NOT. There she goes slamming doors as we speak she must have nothing better to do.
I live in a home that is basically a duplex. My BF's mother lives below us. We have all moved in a year and a half ago and let me say we have had to adjust daily in this time.
I used to cringe everytime I heard a door slam, a dog bark or the washing machine running at 5am. Until, I went down to her floor one day heard the thunderous noise coming through the floor that was my children. I looked at her and said "My gawd woman I cannot believe why you have not killed us by now" I could fill pages of instances of this and thats and I am sure she would have just as many if not more.
The bottom line is you are residing in bascially an old home that was converted to apartments and it's store. Everyone will hear almost every little noise etc. Sometimes you have to take a few steps back and think about what the other person is adjusting to. I refer to it as putting yourself in their shoe's.
Maybe you two should have a drink one night and get to know each other that may be a way to bridge this gap and work towards co existing in the same place.
