Elderly downstairs neighbor complains about any noise and hits her ceiling with something every time I make a noise, like dropping something, or walking too heavily. She has complained to management. They have told me to ignore her--"she tends to be trouble". Now I'm told if there's one more complaint, I will receive a written warning. I feel like I can't move in my apartment! I don't want to confront her--she gets upset easily and has a bad heart. What can I do? Anyone with similar problem? Should I see a lawyer?
