You were outside your girlfriend's house, and working on the new car she just bought. It was amazing that she just got her driver's license before you did, but you felt bad that she had to drive this old hatch-back that her father gave her. Still, you had to fix the engine, so she would be able to get to places.
All of a sudden, you see a weird looking necklace. It had a ruby gemstone, and was all black. "What's this necklace doing on me?" You ask. "I don't remember putting this on. I don't even wear jewelry when I'm out on dates like this." You decide to take it off, after you finished fixing the engine of your girlfriends car, but to your surprise, even though it was around your neck, it wouldn't come off. You even tried prying it off with the wrench in your hands. "What's wrong with this thing?" You ask.
