A gemini without a twin has to exist for two in order to support their phantom half. To feel alone as a child, especially for an only child, is a normal behavior manifesting in the constant seeking of company to balance a childhood of solitude.  And so we embrace imaginary worlds, with imaginary friends.  To carry that quest into adulthood is suspicious of an arrested development leading to a lifetime of groping in the dark for a vaporous someone.  Still alone when we reach out to embrace the empty air and with every loss chipping away until it erodes under their feet.  Each loss a devastation where their air fans at fires and turns waters into tides. Without a sense of solid earth we each suffer.
