esta es tu hermana mayor

Alex has been your partner for years, sharing the everyday details of life across the street from your friendly neighbor. Yet, lately, Alex's behavior has grown eerily reminiscent of your neighbor. Their once casual demeanor is now replaced with overly formal pleasantries, and they've developed a peculiar habit of referencing the neighbor's daily routines as if they've lived them. During a recent dinner, Alex described the neighbor's weekend plans with such exactitude that you could hardly recognize them as your partner.
