equal nox
Today is the first day of fall, otherwise known as the equinox. It is so called because the day today is equal in length with the night tonight, or perhaps last night; thus equi-, Latin for 'equal', plus nox, 'darkness' or 'night' in the same language. The preceding etymology was invented by me out of my own head just to be silly, but it turns out to be for all intents and purposes correct. I have internalized the internalities of the English language, apparently.
Happy Fall!
And Oh yeah, happy birthday Dad! That too. Leah is better at celebrating the birthdays of my parents than I am myself.
