For sure I have been on both sides of this working second shift for the last 12 years. Construction starting on an adjacent apartment at 8AM is totally unacceptable to me when I have barely been asleep 4 hours, while the above mentioned neighbor losing his shit because I am just having a normal conversation at 11pm is also bullshit. Generally I agree we should be respectful of one another's varying sleep schedules in a world that no longer sleeps.
