Saturn square Pluto

What does Saturn square Pluto mean in the natal chart?

Your Saturn and Pluto press against each other, and responsibility tends to land on you in heavy loads, the kind that would flatten other people, through stretches of tearing down and rebuilding. The trap is carrying alone what was always better shared, and burning out with no one even noticing. You're remarkably durable, but you don't have to prove it by doing it all unwitnessed.
