Try it out on mom!

Having read this letter, something comes to your mind others would find rather inappropiate. You wish to try the ring out on your mom. You head downstairs and find your mom watching TV. "Hey sweetie, and what was in the package?" your mother asks, clearly curious about this delivery. "Oh, it's just a ring. I believe one of my friends got it for me." You continue: "In fact, I actually want to show you something it can do, mom."
