Two weeks ago, my Argentinean sister, Lara, arrived in Albuquerque. We don't share any blood, but I spent a year living with her family in northeastern Argentina and now she's spending a year with mine. While I developed a taste for the bitter Argentinean tea, mate, and melted in the heat of sub-tropical northern Argentina, Lara is learning to love tortillas and delighting in the snow. Though sharing space with someone else isn't always easy, inviting an exchange student to live with you can be an incredible experience.
