Really, who knows what Labor Day means besides just a free day off of work? Please do enlighten me if you know because I honestly don't have to time to filter through Google's 110 million hits explaining it.
What I can tell you is what Labor Day means to me. Ironically, 3 years ago, as everyone else was enjoying a day off, eating hot dogs, throwing Frisbees and the like, I was literally going into LABOR! Like, gonna-have-a-baby, don't-even-think-it's-cute-to-make-a-joke-right-now-about-"labor", labor. Yes, I made my transition from hulking tank of 9 months of DQ Blizzards, prenatal vitamins and backaches, into a mother, all in the blink of an eye. (or 19 hours of backbreaking labor...but who's counting?)
So, as you are doing whatever it is you do over Labor Day, just be thankful yhou arem't in ACTUAL labor!
