“Well, this is interesting,” said Daniel, his voice bubbling with mirth. He had been "tidying up" in the study, a chore his wife, Chloe, loathed. He'd discovered a password protected spreadsheet, marked “Investment Strategy,” hidden within Chloe's financial planning folder.

He clicked it open. Chloe had a knack for numbers. He, however, was more of an artist. He began to alter the cell sizes, making them absurdly large and small. He added random cartoon characters, each one assigned a different investment amount. He changed all of the percentages to funny numbers. This would be a masterpiece. He closed the spreadsheet, and the corners of his mouth turned upward.
