Withered and dry, their life is spent. Waiting for a renewal of season, for life to begin again after a cold, painful time. They cling onto the slim arms as if grasping at straws, desparately trying to hold on for one more moment against frozen winds which oppose them.
But they must eventually let go for life to begin again. Indeed, if they don't release their own weight they'll be pushed out by the new life fighting for its chance in the world as spring begins.
Life is such a struggle...back and forth, letting go and renewing. Holding on and losing. Ebb and flow.
