Yesterday, I freaked out because I thought I'd lost my credit card. I remember using it to pay for the movie, and I remember having it in my hand with the receipt in the line, and then minutes later, when I opened my wallet to get it out, ready to buy food, it wasn't there. I checked both my pockets. I checked my shirt pocket. I looked down at the floor. I seriously could not understand what happened. Where the hell did it go?

I had a thought, and I opened my wallet again, and flipped over the flap.

I'd put it in the wrong slot.
