In Berrien Springs, a diverse community with people's from fifty (some say eighty) countries around the World, I was impressed by the courtesy at the corner gas-mart. Everyone held the door open for the next person. After passing through the doorway, having the door held open for them, they would then take hold to allow the next person through. I had the opportunity to go into the store four times within an eighteen hour period. Each time I had the same experience. Young or old, well dressed or sagged panted, the good practice of civility held true for my every visit.
There was no one to hold the door for as I left the last time. No reason to exchange the baton with the young man holding the door in one hand, his belt loop in the other.
I would if I could.
