Ms. Lena (pseudonym), the neighbor’s daughter, moved into the villa across the street a year ago. A quiet introvert with a penchant for water sports, she quickly identified my backyard pool as her personal training ground. At first, I dismissed her presence as a minor nuisance—a woman in her swimsuit diving in and out of my oasis, ignoring the usual formalities of prior permission. However, her persistence soon revealed an earnestness: she was training for a local swimming competition and saw my pool as a convenient, if not ideal, resource. Our initial standoff evolved into a cautious truce, punctuated by exchanges of sunscreen and bottled water.
