"El amor perfecto es el que se lleva a cabo enteramente por correo."

Simplified Meaning:

The quote talks about the idea that a love affair through letters can be perfect because it avoids real-life problems. When people write letters, they often share their best thoughts and feelings without the everyday difficulties that face-to-face interactions can bring. In real life, people might argue, get annoyed about small things, or face misunderstandings. However, writing letters allows them to take time to think about what they say, and avoid these issues. For instance, in history, soldiers and their partners exchanged love letters during wartime, holding onto an idealized version of their relationship. By communicating through letters, they kept the romance alive, without the hardships of day-to-day life interfering. Following this idea in real life, someone might focus on the positive aspects and deep thoughts in their relationships, much like writing a thoughtful letter, to keep their bond strong and meaningful.
