No such thing. Every time I finish the dishes, fold and put away the last load of laundry, rake the last leaf, dry the last tear, I think of “it” as complete. Finally. Yeah, right. Not in this universe. The space/time continuum is a Möbius strip, going up the stairs in a drawing by M C Escher or the ones at Hogwarts, the original Never Ending Story, the Windmills of Your Mind… Is that comforting or terrifying? Depends.
