Almost everyday I pass road construction guys. They stand out there with a stop/slow sign wearing a hard hat and orange vest. I like waving at these dudes or at least smiling (not in a slutty "come over here" way) and then seeing them wave back or at least give me a head nod. That's got to be a pretty wretched job, especially when it's 104 degrees and they're wearing blue jeans. So I'm happy when I can make them smile. They are important, they keep me from having a head on collision with on-coming traffic. A smile is the least I can offer. And if they are happy maybe they will hurry up, finish their job and get the hell out of my way.
