It's a tie be tween my house key and a good luck charm I wear around my neck. The good luck charm is simply a silver locket with a bit if turquoise on it that came from nepal, It used to have some seeds in it, but now I keep something else in it. My house key is also here because for one it means I have a home, and for two, I love unlocking and locking my door with it. It slides in nicely and does the most satisfying click ever. I honestly could spend all day locking and unlocking my door, it's that good.
