Lesson: When your kid wants to trade you a quarter because it’s too dirty, just do it. Your kid just might be correct.
Story: Instead, after making out the three barely visible words “tails you lose”, I tell him it isn’t a quarter, it is a flipping coin, and that we should clean it and see what it looks like – brilliant idea Dad! So after much scrubbing with no results, I soak it overnight. This morning the substance was easy to scrub off. Now – time to explain about heads and tails.
