I, uh, don’t wear any pajamas so imagine my surprise when, getting up in the middle of the night to go to the bathroom, a quarter fell off me and landed on the bathroom floor while I was standing there.
I found out later my SO had cleaned out his pockets before making the bed and probably lost a quarter on the sheets, which then stuck to me, and then fell to the floor when I got up. (Another reason mom was right when she said not to put money in your mouth, you don’t know where it has been!)
Maybe the $2 got stuck to the bottom of a stack of papers or notebook?
Then again, maybe money really does grow on (Canadian) trees and your desk just bore fruit?
