There are some things that go with living in an apartment building. Hearing some of what your neighbors do is one of them. You have no way of knowing what she’s doing up there. She could be moving about her apartment completely oblivious of what you’re doing.
Also, even if she is listening to you, why do you care? I’ve lived in apartments before, and if the person above me wanted to spend their time following me from room to room and listening to me make breakfast, watch TV, and do my laundry, why should i give a damn?
