Thank you, everyone!
I don't know if it's the nature of the transits or simply a matter of age, but I've been much more nonchalant than I usually am on my birthday; I've only told one or two people who didn't already know, and only because it fit in the conversation.
Do you suppose this may be indicative of the Capricorn Ascendant in my solar return chart? I haven't really bothered to study it because I haven't gleaned much significant information from solar return charts in the past several years. My only major concerns are a tight Mars-Saturn opposition and Pluto hovering in my twelfth house within six degrees of the Ascendant, but I've got some nice trines and sextiles to make up for these aspects.
