Ok, ok. Lori, when I see you with a flat tire I promise I will stop and change it for you. If you pull a colt .45 on me for my efforts, I hope it is only a cold one from a six-pack.
When I was a teenager I hitched-hiked many places including to school. I'd never do that today if I were a teenager, and NEVER do I ever give a stranger a lift these days.
Once when I bummed a ride, I remember some unpleasant events were starting to unfold and I smashed the driver in the face as hard as I could, almost causing an accident, before jumping out of the car. I was so scared that I flew over a fence between two houses. For a month after I tried to jump over that same fence under more favorable conditions, but could never even get close to the top -- talk about what adrenaline can do.
What I am trying to say is that through my own life's experiences I have formulated the mentality that oozes the urge to stay out of strangers-on-the-street business. I'm not saying I don't help strangers -- rescuing the drowning fishermen, for instance; but in the city, on the road, in a restaurant or a mall, etc., you have to watch your back and think out your decision carefully before you make your move.
This is only my opinion, and I'm sure there are plenty of people who can't wait to help others. My hat is off to them.
