. . . Using the most unpractical and time consuming way, as always. :P
Me and my mum have been having some trouble with some dickhead kids lately who like to swear at us and enter our garden from the nearby woods (we're getting a fence soon) while throwing stuff at our buildings. I hid once and took their photos, so now the police are interested in finding them 'cause they've been breaking into other people's gardens too.
Since I have the time (kinda) and like walking around the area when I have the opportunity, I also tried following them a couple of times to see where they'd live, so that I'd know where to go if they did any real damage when we were away or so. Unfortunately I keep losing them 'cause they run through other people's gardens and I can't follow them without trespassing.
Anyway, to the point (if any of you are still reading this, which I doubt). My mum stumbled upon a Den that they spent ages and put a lot of time and effort into building. Not that it's a bad thing - It's better then sitting on their arses playing games all day. But in the process they destroyed some live trees and they blocked a footpath (which is how she stumbled upon it), essentially damaging some ancient woodland. They also crushed some Bluebells (flowers that are rare in Essex and mostly grow in woodland areas), and it'd of given them somewhere to hide when I chase them from the garden. This pissed us off.
So we thought "Sod 'em, this ain't staying here", grabbed some tools and a wheelbarrow, and set about clearing it.
I've now got a nice pile of firewood thanks to them.

Hehe. Be nice for the wood stove that Alector resurrected once we get it installed.
So we cleared the pathway 'cause no-one else would've been bothered to do so (they'd of just walked around, crushing more bluebells). Most importantly we "got rid of" all of the wood so they can't re-build it.
And a little message I left for them telling them what they can and can not do (which they'll tear up and ignore, but what the hell). It's signed "Pikey Bastard" 'cause that's what they yell to me when they see me. So I guess that's my new nickname, even though I have a fixed address, don't live illegally in a caravan and don't go around living in random fields, trashing and destroying every single one I leave behind (real gypsies don't do that. It's the 'Pikeys', the trailer trash that give 'em a bad name, but that's another story).
Of course this'll piss them right off. Just 'cause thier parents can't teach them to respect people's property and nature, doesn't mean I can stand by and let them get away with whatever they want.
He who has the last laugh, laughs loudest. :P And gets some free firewood too.

That'll save me some time later, maybe it'll make up for following them around and failing to find where they live.
I'll bet their reaction will be to enter our garden and try to vandalise our property again, though. Still, thier loss.
