I actually feel a twinge of guilt when I drive by someone broken down even if I have no tools or skill to help... and I see the person on the cell phone calling for help.
I've helped pushing cars while others stood around and watched, or helped a couple of people half my age so that they could get the car off the road sooner...
However, in this case, I just decided to watch and see if you were really strong enough to do it yourself.
Just kidding!
