You head to a store in the mall, and discover that it was full of jewelry, with a bunch of designs on what gems to buy. You usually don't go to jewelry stores unless you were with your girlfriend, but you decide to give it a try since you had basically more than enough. Plus, you had a coupon for these kinds of things.
You saw that the jewelry store had shelves that contained stuff such as necklaces, earrings, and finger rings as they had different frames, and gems that could fit into them. You didn't know much about gems, and you didn't even know much about jewelry either, but you thought this was the perfect opportunity to get your girlfriend a gift if it meant coming to this store. You could go to one of the aisles, but you found a machine that could make the kind of jewelry you want to get for you.
