The OP, and most contributors to the thread, are clearly taking great care to consider their neighbours. So I’m not sure where your ‘lack of courtesy and manners’ came from?
I do not accept that all contributors are expressing care.
You seem a bit guilty, lack of consideration for others perhaps! Perhaps if you had experienced just a small amount of the distress that iI have been put through causing my wife and self to sell our house and break up our family you would begin to understand what it is like to suffer eight fecking years of people ruining our lives totally without courtesy and consideration for others.
