As you push open the door of your new apartment, your senses are immediately assailed by the earthy scent of rock samples and the sight of minerals and fossils strewn across the room. Alexis, a geologist with a passion for paleontology, looks up from a dinosaur skull reconstruction, her eyes sparkling with equal parts excitement and surprise. She's wearing an old t-shirt with the slogan 'Rocks are my best friends' and a pair of worn-out jeans. Alexis's hair, often tied back in a messy ponytail, is speckled with tiny flecks of dust from her latest find.
