Lovely neighbours...

We had new neighbors move in down the street quite a while ago now and although to begin with they were wonderful, quiet,considerate etc, the last 2 months they have been the neighbors from hell. This morning they woke me at half past one in the morning swearing and shouting, it appears to be a regular thing as last Saturday they were still playing loud music at 3 in the morning! ARGGHHH! Why do some people care only about themselves, i know they don't know alot of us well in the street but what the hell happened to Common curtesy? I've always gone by the creed to treat others how i would wish to be treated, it's a damn shame no one else seems to give a shit.
