The sound issues are real. Lowell should tighten up the local building code wrt sound isolation. I'm lucky wrt considerate neightbors. I've grown to like hearing some 'sounds of living' from the neighbor upstairs. 'Attitude adjustment' and 'having realistic expectations to start' are coping mechanisms.

Some noise happens like clockwork and that makes it easier to take because you know when it is going to stop. I put on my noise cancelling headphones for 20 minutes at the same time every week.
