OH-NO.

"Oh no!" is not a scream of fear -- it's a form of supreme intelligence. When a normal person sees a cup on the edge of a table, the Oh-No Person sees a disaster epic composed of "water stain - short circuit - fire - building evacuation - economic losses - butterfly effect - end of the world." And so, with an "Oh, no!" erupting from the depths of their soul, they move the cup to the exact center of the table at lightning speed, then place a coaster underneath for good measure. The Oh-No Person has an almost obsessive respect for boundaries: yours is yours, mine is mine. Every accident and risk has already been strangled in its cradle by their perfectly timed "Oh, no!" They are the guardian deities of order, the last batch of respectably uptight people holding it together in this chaotic world.
