A neighbour of mine, living right above me, has tied plastic straps to her balcony railings. Every time there is a bit of wind, they flap really noisily. This noise is both irritating and constant. On hot days, whenever I open the window for fresh air, those flapping straps are a constant, maddening noise.

Talking with her has been futile. Not even an apology for the inconvenience. She claims she needs those to scare birds away. I mentioned that we all have issues with birds, but I haven't seen anyone else install noisy bangles on their balconies. I offered her a couple of alternatives (e.g. I myself put up spikes on my balcony railing to deter birds from landing, and it is working quite well).

Nothing. Her attitude has been “me, me, me.” Never before have I encountered a person so selfish and so indifferent to the nuisance she is causing.

The issue is silly, yet I work from home and have to deal with it every single day.

What can I do?
