In 1981 Labor Day fell on September 7th. I was born at 8:33 pm on September 8th after 23 hours of labor. I think it was 23 hours, I'm sure my mother will correct me if I'm wrong. In any case, I've always considered it a fun little anecdote that my mom went into labor on Labor Day. My Dad was working overtime and, the story I've always heard is that, when my mom told him to come home he correctly predicted my gender saying, "It's a girl. She's already costing me money."
Labor Day is supposed to be a day off for working citizens. In 1981, my mom sure didn't get the memo on that one. Or maybe I was the one who didn't get the memo.
*****Update*****My mom clarified, in the comment section, that my dad had not yet left for work. He was, apparently, walking out the door when her water broke. I suppose he still could have gone to work. I wasn't born for another whole day, after all. Not that I'm suggesting that he should have left my mom, mind you. I'm just saying, he shouldn't blame my gender for lost wages. It was his choice. Am I right?
