When I get home after work, I usually put my keys and my door pass in my hat, and then I leave my hat on the side table.
However, I’ve recently bought a set of Hogwarts school ballcaps. I pick one at random in the morning and wear it to work. When i get home from work, I put the Hogwarts hat back in the pile, and the keys and door pass end up in my old hat.
Yep. Forgot the door pass today.
I sit in the lobby and wait for the receptionist to hand me a temporary badge.
