Why does Juan take a job as a censor?

Poor Juan! One day they caught him with his guard down before he could even realize that what he had taken as a stroke of luck was really one of fate's dirty tricks. These things happen the minute you're careless, as one often is. Juancito let happiness-a feeling you can't trust--get the better of him when he received from a confidential Source Mariana's new address in Paris and knew that she hadn't forgotten him. Without thinking twice, he sat down at his table and wrote her a letter. The letter that now keeps his mind off his job during the day and won't let him sleep at night (what had he scrawled, what had he put on that sheet of paper he sent to Mariana?). Juan knows there won't be a problem with the letter's contents, that it's irreproachable, harmless. But what about the rest? He knows that they examine, sniff, feel, and read between the lines of each and every letter, and check its tiniest comma and most accidental stain. He knows that all letters pass from hand to hand and go through all sorts of tests in the huge censorship offices and that, in the end, very few continue on their way, Usually it takes months, even years, if there aren't any snags; all this time the freedom, maybe even the life, of both sender and receiver is in jeopardy. And that's why Juan's so troubled; thinking that something might happen to Mariana because of his letters. Of all people, Mariana, who must finally feel safe there where she always dreamt she'd live. But he knows that the Censor's Secret Command operates all over the world and cashes in on the discount in airfares; there's nothing to stop them from going as far as that hidden Paris neighborhood, kidnapping Mariana, and returning to their cozy homes, certain of having fulfilled their noble mission. Well, you've got to beat them to the punch, do what everyone tries to do: sabotage the machinery, throw sand in its gears, get to the bottom of the problem so as to stop it. This was Juan's sound plan when he, like many others, applied for a censor's job-not because he had a calling or needed a job: no, he applied simply to intercept his own letter, a consoling albeit unoriginal Idea. He was hired immediately, for each day more and more censors are needed and no one would bother to check on his references. Ulterior motives couldn't be overlooked by the Censorship Division, but they needn't be too strict with those who applied. They knew how hard it would be for the poor guys to find the letter they wanted and even if they did, what's a letter or two when the new censor would snap up so many others? That's how Juan managed to join the Post Office's Censorship Division, with a certain goal in mind. The building had a festive air on the outside that contrasted with its inner staidness. Little by little, Juan was absorbed by his job, and he felt at peace since he was doing everything he could to get his letter for Mariana. He didn't even worry when, in his first month, he was sent to Section K where envelopes are very carefully screened for explosives
