You know how annoying it is to have to wait for the semi-truck to turn left in front of you?
On my way to work the other morning, a trucker was turning into the street where I was approaching the intersection. I stopped several carlengths from the corner and flashed my lights at the truck. The driver made his turn after he flashed me a big grin and a two-handed wave. It sure made my day, and I think it got his off to a good start, too.
Paying it forward can be a real booster to both the giver and the receiver; I hope we all can make an opportunity for PIF every day!
