Technically, I suppose, every day is a cusp; every moment, for that matter. We are always at some point of change, which is as it should be. Astrologically, I’m a Capricorn on a cusp with Aquarius, meaning that my sun sign is influenced by the next celestial house—not that I believe in astrology, but there are a good many Capricorn characteristics I favor, and they were “mine” long before I knew what astrology was. But today my cusp-edness concerns a project that, if it is concluded successfully, will bring broad grins to many of my friends—and grimaces to a clump of others.
More to follow. Your patience will be rewarded.
