That’s the number on my locker. Wanna see it? Sure, here it is:
6 out of 7 days of the week I go to the library. None of the lockers belong to anyone by the way.
Anyone can choose whichever locker they want on any given day of the week. You come, you pick one, you go, you leave it open.
Then how come on all 6 days I get to use that same locker, again and again and again?
Why can I walk around and tell everyone with 100% confidence that that’s my locker, number 3104, Nik’s locker?
Here’s why (and why you should care): because it’s on the bottom.
