Single like a pringle and ready to mingle, woo woo.
By sign: When a planet is in, take your Mars for example so Capricorn, it automatically squares (that is, goes against) the planet of Jupiter because it is in another cardinal sign that isn't its opposite. Cardinal signs see one another by angle, so, you can say that the two "hold different opinions but haven't started arguing yet" due to the "by sign" square.
I have never heard of this concept before. Heard of squares etc but not by sign. Thank You.
No, no BLAZE! not single like a PRINGLE lol. I'm not sure if you have the same ad's as the UK but a pringle once pops just can't stop lol
