You mean if the sun died? Well, we'd have about 8 minutes of sunshine, and then the earth would become a frozen husk within a day. And we'd all become frozen in a stasis, forever until even the ice lost it's integrity, and then we'd shatter and become dust. What could anyone do?
God, that's depressing.
Get reaquainted with my blind friend and let them feel what it's like to have the upper hand.
Sit back and listen to those around me run around like chickens without heads
Light a candle and hope it comes back on.
