How do I deal with this neighbour?
context: I just moved into a new apartment on the 4th floor and the person below me left this note, they already left me another note the day after I moved in that was much nicer just telling me that the building was badly built and to please walk quietly If I can, but I find this pretty concerning.
FWIW i have been pretty quiet, especially at night
i have never met this person or interacted with them in any capacity,
