* I am much too much of a control freak to ever ever try drugs; no moral issue, just not for me.
* I have a drink of something on social occasion maybe once or twice a year, maybe not. Never got behind the wheel with even a sip of alcohol that day, let alone a glass, let alone anything approaching legal limit.
But I'm a klutz and I'm an introvert and I get nervous easily and I have NO idea what kind of "signs" my body would display in stressful situation with a police officer at night (my body an my brain have an uneasy working relationship - we mostly put up with each other:).
It is very literally my nightmare scenario to be accused by a police officer of intoxication where none exists. As much as I 100% support them, I'm probably more afraid of roadside checks than an actually inebriated person.
