So, on my way to work each morning, i like to put the windows down, cruise, and perhaps even sing along to my iPod.  This morning in particular, I was singing at my normal Windows-Down-Not-Hesitating-65mph-Sometimes-Fake-Microphone-In-Hand singing voice, but instead going only 5mph.  I didn’t realize I was singing at flank volume until I noticed two construction workers in the distance — far distance, mind you — who were quietly shoveling and minding their own business, suddenly stop what they were doing, look up in my direction rather quickly and give me one of those blank and confused doe-in-the-headlight looks.  i passed by, laughed, though slighly embarassed, but kept on singing (just not as loud).
