Hello
PrimeTimer, I am very sorry about what you are going through right now and I do hope that partygirl goes through "a very short phase" of all this and hopefully "things" calm down very soon...
... We had something similar here at one time when a neighbour's teenage-boy went "through the phase" of "listening" to very loud reggae music which made our ears and walls vibrate...
... Fortunately it was "only" a phase and fortunately he calmed down after a while and all of us could go back to read a book and breath calmly again...
... I keep my fingers crossed and hope that partygirl's phase does not last that much longer anymore and I send you all my sympathy ...
Best wishes from Kristina.
