I should mention that most of us don't have A/C and those that do avoid running the window units at all costs because of the toll they take on the electric bill. So, we all have our windows open all.the.time... advantageous for the trade-winds coming off the ocean, not so much for quiet.
Everyone has told us to simply confront them and "kindly remind them you live below" but, I just don't know if I can do the "kindly" part... and honestly how can they NOT realize how extremely loud they are?!
I know there are other "neighbor/apartment horror stories" out there... let me hear them!
