One dollar? 

Comin' right up. In the form of my super-duper trusty-rusty handy-dandy ATM CARD.

Everyone was all: DUDE - that guy's RAD! Stand back, he's whippin' out the plastic.
But it wasn't in the pocket I thought it was in. I felt three, four times just to make sure. Nor wasn't it not in the pocket I didn't think it was in. It wasn't in either pocket.
No, that's impossible. I quite clearly remember picking it up off the floor. I may be stupid, but I'm not an idiot. Possibly I mis-felt? Did I put it somewhere unusual? My sock? My shirt pocket? It must be somewhere on my person!
All right, what the FUCK???  Did I have it at all when I left the house?  Was I holding it in my hand and I just absent-mindedly dropped it?  How should I know?  Why don't I take better care of my things?   OF ALL THE PRECIOUS THINGS YOU OWN, YOUR ATM CARD IS THE MOST IMPORTANT.  AND NOW IT'S GONE - YOUR ATM CARD IS GONE.
IT'S GONE, AND EVERYONE IS STARING AT ME.
