Losing money

Yesterday, I had a $20 bill in my pocket. Then, I went to the gas station and spent a good five minutes on my hands and knees, adding air to my tires. I came home and changed into my comfy house clothes then changed back into my street clothes for a class a few hours later.

My $20 was gone.

Where did it go?

It's a mystery.

The current tally of money I've managed to lose since December 24 is $70.
