I live in a apartment complex and I have two neighbors - Martha and...let's call him "Shaggy" (you'll get why). Martha is a sweet old lady and Shaggy is...a total and utter anus. He complained about the noise when I moved in (although I tried to be as quiet as I can, SOME noise just can't be avoided), he complains about the noise if I so much as sneeze and woe be me if I forget to clean the hallways when it is my turn. His favorite saying? "WE HAVE RULES IN THIS HOUSE!". Whatever I do wrong, even the smallest infraction that a normal person would either overlook or seek a private talk about, got reported to the house owner - or the cops. I have nothing but trouble with this mofo and I hate his guts.

One day, I got the cops called on me due to a noise complaint at 9:50 pm (house rules say that you have to keep the noise down "to apartment level" starting at 10 pm). I immediately knew that the "culprit" was Shaggy because Martha not only does not give a damn unless I make so much noise the entire complex is shaking on its foundations but is also completely deaf without her hearing aides - which she removes every day at 8 pm, sharp. While the cops are snooping around my apartment (they were called because there were screams and curses coming from my apartment and they wanted to make sure I had not killed anyone, even though I had just burned myself something fierce on my stove and had vented my pain and frustration) and generally being a bother, one of them suddenly asks me "Do you smoke weed?" and points out the window at the playground behind the complex. And that was when it hit me.

Cannabis may have been legalized here in germany, but the law states that there are places where you are simply not allowed to light up - like in the vicinity of playgrounds, schools, childcare facilities etc., makes sense, yeah? And Shaggy is a freaking stoner. Walks around with red eyes, his apartment and clothes reek of the stuff and I have never seen him sober. He is constantly high as a kite, which makes arguing with him both scary and funny.
Well, anyway, the playground behind the apartment complex means that the entire complex is a no-weed zone (even if you only light up indoors). Now, normally I wouldn't have said anything, because I ain't a snitch and Shaggy keeps it indoors. But like I said, Shaggy is a b-tard and a stickler for the rules. Well, two can play that game.
I eventually got the cops off my butt (after they had looked into every nook and cranny and found no corpse) and told them to check out Shaggy, telling them about his weed use near a playground. Guess who got his apartment searched top to bottom and eventually arrested when he tried to attack a officer because he DARED to touch his stash? WE HAVE RULES IN THIS HOUSE, SHAGGY!
