Because you always wanted to know
According to Dave’s mom, today is called Christmas Adam (because Adam comes before Eve). Now that you know this, you’ll find you can use this term all the time. Because, really, all sorts of holiday events often happen on Christmas Adam. I have incorporated this term into my lexicon for so many years I forgot that it’s not well known (I said something to Eli about how we were going to bake cookies on Christmas Adam, and my mom, overhearing, wanted to know what on earth I was talking about). So, go forth! Have a lovely Christmas Adam!
