Recently, they have moved next door to me, bought a house, which I should have bought. My wife is still furious why I didn't buy it. But that's another story.
I already have few running with them. Two of the midget brothers were about to get it right between the eyes. But their elder brother is more sensible, he apologised to me and promised that his younger brother wouldn't try to steal part of my parking space on regular basis.
They have 4 cars, and think they own the street now. They park every night blocking the path to a common right of way. I can simply report it to local council with photographic evidence and get their car pounded.
