We're learning how important it is both to preserve sibling relationships if they work and repair them if they're broken. We're also learning a lot about nonliteral siblings - stepsiblings half-siblings - and the surprising power they can have.
Life is suffering. Life is not resistance to suffering. The point of life is to suffer. This is why we're here: We're here to suffer. I believe in a higher power that compassionately allows suffering for us as a race to grow and mature.
