At 4:32, I need to go to the store. It has to be at 4:32, because it takes exactly eight minutes to get to the store, and I have to be inside of the store by 4:40, because shopping for groceries always has to begin exactly at a ten minute interval.
I need to make a list of what I need: apples, oranges, birth control, condoms–but wait, that list needs to be in alphabetical order: apples, birth control, condoms, oranges.
I need to map out which aisles I’ll be going to, in descending numerical order, before I get there, so that I can be sure that I’m out of the store by five o’clock; shopping for groceries can take no longer than twenty minutes. Apples and oranges are in aisle four, birth control is in aisle three, and condoms are in aisle two. 4:32, perfect–but wait, I can’t go back to aisle four to get the oranges once I’ve already gotten the apples–that wouldn’t be in descending numerical order–so I guess I can’t buy oranges today.
Now then, the list reads: apples, birth control, condoms. ABC. 4:32. Perfect. I’ll spend five minutes exactly in each aisle, and five minutes exactly at the checkout, to ensure that I am walking out the door exactly twenty minutes from the time I walked in.
…Fuck, it’s 4:33.
