i never call the cops unless someone's life or limbs are in danger

nothing good can come from calling the police, they are not your friends and they are not there to help you. here's how the conversation goes:

tattletale : "this guy is illegally parked on 40th st"
police : "oh yeah? what are YOU doing on 40th st and why do you care?"
tattletale : "just minding my own business"
police : "oh we have a smart ass, i think we'll haul you in for questioning and search your house and car while we're at it"
