When a neighbor says she cannot sleep when I droppped a tiny keychain [only] on my porch ??! I never heard of people with hearing that sensitive.. I really never heard of such a thing /then she says to me from her window when I'm on my porch to not do that ! Very annoying to me! It is my life I can go in and out of my place as I please! 

This is the third time she did this ..Some people wish for a 'deader then dead' quiet atmosphere more as a morgue lol! I can sleep very easy thru a metal pin dropping.In my apartments people want it so quiet that is too much.I do not make any real sounds at night period. 

Buy your neighbor some ear plugs - they are cheap on amazon :) 

David I never heard of a person with hypersensitive hearing that way ! lol. I have to really wonder about her or/and I think people like her 'think' they need to act that way because of the area or something.. 

When I was still in AL, I had a guy who lived below my apartment knock on my door at 5:30 to complain about me watching youtube videos on my laptop. Those apartments were super old, I just got used to hearing racket from other units. Plus my bedroom window was about 5 feet from the playground. He was a cranky old geezer though.
