I think one of the main things about acclimating to small town life is getting used to local habits and vernacular. It's those little things that can really define if you are a local inhabitant or merely a transplant. For example let's discuss the fine art of, "speaking", while driving.
The first real rule to know is that you speak to everyone. Yes, it doesn't matter if you know them or not. They deserve at least the one finger wave. You know.....lifting one finger off of the steering wheel to acknowledge a fellow driver passing by.
Now....if you really want to get friendly, you can give a two finger wave. What is the difference you ask? Well, maybe it is just that certain something eminating from the passing car. Perhaps you know them just a tad. Or, maybe you just have a little more enthusiasm to offer.
Speaking of enthusiasm, let's talk about lifting all fingers off of the wheel. That bit of whimsy when you feel all giddy about waving to someone. Or, perhaps, they gave you a big wave and you want to send one in return.
There have been times when I have actually lifted my hand off of the wheel, yes dad it's true, to speak to someone. But, let's forget that ever happened and keep it on the down low.
However you choose to acknowledge your fellow man, let it be in kindness.
Speak, give a wave, and a little back.
