Key Word "SEEM", it doesn't mean we are. My friends always ask me that similar question. I am not sure if it has to do with Astrology, I always assumed it was because my dad and brothers always told me not to cry over anyone and to be strong. Because if I showed any kind of sadness in front of them, it would break them apart. And that to me hurts more.
As a Capricorn woman, I think we are good at pretending not to care.
