If you had a cat and you filled the bowl with food the cat would eat out of the middle pushing the remaining food to the sides. after the cat finishes all the food the cat will start mewling for more
THANOS:
THE AMOUNT OF FOOD IS PERFECTLY BALANCED; OPTIMIST: THE BOWL IS HALF FULL; PESSIMIST: THE BOWL IS HALF EMPTY; WHAT IF I TOLD YOU THAT THE BOWL HAS FOOD; THE BOWL IS EMPTY; THERE IS NO FOOD
