The Light in Apartment 4B

Every night at exactly nine, the light in apartment 4B came on. Mara noticed it during her first week in the building. She was unpacking boxes, eating dinner from a paper plate, and trying not to miss the home she had left behind. Across the narrow hall, the old woman’s door stayed closed, but a warm line of light appeared beneath it each evening. One night, Mara held the elevator for her. “You’re kind,” the woman said, clutching a small paper bag. “My son used to do that.” Mara smiled, unsure what to say. The woman introduced herself as Evelyn and disappeared into 4B. After that, they began exchanging small courtesies: a returned package, a borrowed cup of sugar, a brief conversation by the mailboxes. Evelyn never spoke much about her son, except to say that he lived far away and had promised to visit. Then, one Friday, the light did not come on. Mara waited until morning before knocking. No answer. She called the building manager, who found Evelyn asleep in her chair, weak but safe. At the hospital, Evelyn asked for one thing: the paper bag from her kitchen. Inside it was a stack of letters, all addressed to her son. None had been mailed. “He said he’d come when things got easier,” Evelyn whispered. “I didn’t want him to feel guilty.” Mara offered to help her write one more letter. This time, Evelyn chose different words. She didn’t ask him to come back or explain the years between them. She wrote only that she missed him, and that the light was still on. The letter went out the next morning. Weeks passed. Winter loosened its hold on the city. Then, one evening, Mara heard footsteps in the hall and a knock at 4B. The door opened. A man stood there, holding a suitcase in one hand and an unopened letter in the other. That night, the light came on again. But for the first time, it wasn’t waiting for someone to return.
