living in a block of units. the neighbour next door complains about every single sound. We can't walk past the window of hers talking quietly without her poking her head out and whining. now that my brother has moved in, and they don't get along, she's gone wild with it, and has called the police, complaining. We're not making alot of noise!! one more complaint from her and we start to get into real trouble. where do we stand on this?
