Whilst I would not recomend this sort of action, I had some ''little scamps'' knocking my door, then banging my window, then throwing stones through windows last summer.
Being the gentle-natured (ahem) person I am, I organised one of my mates to stand behind my front door, whilst I stood out the back.
When they next tried banging the door, he leapt out and chased them around the back lane.
I then pounced and caught one. Needless to say, this little 5h1t wasn't expecting this, and he ''fell down the stairs'' (to coin a police term).
After a stern talking to, I promptly marched him to his parents house where his mum ensured that he toed the line.
Not had any problems since - whilst I don't condone this sort of action, it's the only way some kids will listen.
Funnily enough, they started doing it to someone living behind me - they stopped after he chased them for ages waving a metal bar - strange that!
