It may have been an innocent thing on your part that in the heat of the moment you may have lost track of time while doing your music ...
It can happen to the best of us....
The fact that you were threatened by 2 people on your doorstep brings this thing into Major Red Flag territory...
IMHO, You would have been much better off if the police had knocked on your door because they would have treated you in a much more civil manner . You would have been a low impact call for them in the scope of their shift that night.
After a little chit chat you would have been in a better position than you are now because they would have had to document the nature of the call ...
Chances are they would have given you a polite warning , also there would be a record of a possible Rub w your neighbor's in the making ...
OP , you need to take what happened seriously and do everything you can to nip this one in the bud .
If money is super tight for you right now , do a little thrift shopping or go to a Good Will and grab a cheap set of used cans just to start the ball rolling on keeping the peace ...
I sincerely hope that This Rub blows over for all folks concerned ...
