I habitually fouled my neighbours driveway. There has been animosity between our family and the one next door virtually from the outset. The petty bickering continued to and fro for years.
As the middle child I took it upon myself to wreak some retribution on our neighbours and I chose shit as my weapon. About once a quarter I would sneak over the hedge separating the properties and take a dump in their driveway, under cover of darkness.
I was amazed at the size of the produce when it wasn't in it's usual porcelin surroundings. In the next day or so, the family would emerge from their house, wrinkle their noses and spy the big pile of shit. John (the man of the house) usually took it upon himself to cover it up, as you would a corpse, presumably to stop it scaring the children and ruining his wife's hairdo.
Me and dad thought it was absolutely hilarious and the topic was often mulled at family meal time conversations although I never let on that I was the culprit, despite some pointed accusations. In actual fact you guys are the first people I have ever told, a good 15 years on from the original deed (I did it for about a year).
Well, at least I didn't go round and pop a cap in his ass like you crazy yanks, we are much more civilised in the UK.
