I've lived for 31 Labor Days. I'm embarrassed to say that I didn't know what we were celebrating today, so I looked it up. According to Wikipedia,
Labor Day is a United States federal holiday observed on the first Monday in September. The holiday originated in 1882 as the Central Labor Union (of New York City) sought to create "a day off for the working citizens".
My thanks to the Central Labor Union. And to all of you who work hard to support yourselves and the ones you love. Happy Labor Day...have a barbeque!
