We live within creation’s cage: the double twins of space and time, matter and energy. Their impartial rule treats us all alike. Money, hours, and strength go only until spent. Do the taxes, wash clothes, or hold your honey? Choose one. You can take enough fuel to go the distance, but what cargo stays behind? You can make the extra landing for the patient, but sunset will stop the flight short of the hospital. Limits dog life. Neither desire nor worthy need gains their attention. Their hard places define humanness and teach the brutal lesson quickly: There is not enough to go around. Get yours while you can.
