They weren't bad neighbors, all things considered.  From time to time we'd meet on the street, chat about motorcycles, I'd (very politely) decline the opportunity to purchase heroin, and they'd beat the snot out of anyone mucking with their turf.  Petty street crime dropped to zero.  

As long as you remembered they were completely batguano gonzo-crazy ... no problemo.  ;-)
