always admit you're in the wrong. it's an ego stroke- women know how to do it to men, plain and simple:
i got stopped a while back (for speeding, of course on me bike) and as soon as he walks up to me, i've got my helmet off and i'm handing over my papers. (this is where i score my first points and let him know i'm not going to be any trouble) he nods takes the papers and says "do you know why i pulled you over?"
"yes, sir, i was speeding." (this is the correct repsonse. you know what you did to attract attention to yourself. score points with the police officer for letting him be "right" and "in charge")
so in my case, the officer says, "yes, you were, ma'am. please try to slow down. i realise it's hard on that motorcycle- probably a lot of fun to go fast, but this is a residential neighbourhood" blah blah blah
"yes sir, thank you, i'll be more conscientious next time."
"please do, ma'am. have a nice day."
i let him be in charge- it made him feel like he's a good cop and because he's doing a good job, maybe it will be okay for him to go easy on me. after all, i'm just a kid on a motorbike and i didn't give him any mouth, etc. i had all my papers ready and whatnot. but i think, really, if you let the police officer call the shots and you're calm and accomodating, you're more likely to get a positive outcome.
