We had a similar problem here about a year ago re: mailbox and reckless driving with local teenagers. I got fed up with the reckless driving one day and waived down one of the teenagers:
Me: “Hello”
Teen: “Hello”
Me: “About your driving around here, could you guys permanently cool it down a bit?”
Me: “You know, with all the kids and dogs and everything—it’s kind of dangerous don’t you think?”
Teen: “Yea, no, I don’t know”
Me: “Well, a lot of us neighbors would appreciate it if you guys would watch your speed through here, ok?”
Me: “And about the mailbox vandalism, have you heard the saying ‘don’t shit where you eat’?”
Teen: “No.”
Me: “It means don’t vandalize your own neighborhood, you know what I mean?”
Teen: “errrr, whatever dude, lighten up—we don’t do that”
Me: “That’s cool. I’m not trying to be an asshole. No big deal. Hey, what kind of exhaust you got there?”
Teen: “super double muffler j.c. whitney”
Me: “It really sounds good, I like your rims too. Have a great day.”
We haven’t had a problem since.
