I think the 'magic timing' is 11pm?
After 11pm yuo can make official complaints regarding noise
pollution...
imagine you are kindergarten teacher. got a child A who keep
disturbing child B.
scenario 1:
B: teacher teacher! A keeps poking me in the arm!
teacher: A, be nice and don't disturb B.
teacher goes back teaching, A disturbs B, cycle continues.
B feels he has no choice but to summon batman. batman solve the
problem, everyone wins.
scenario 2:
B: A, can you please don't disturb me? It is affecting my
sleep.
A: Sorry, I will not do it again.
B cuts down on the number of times he disturb A, but still does
it from time to time. A understands that getting disturbed is part
of life as a student in a class, and try to accomodate A.
