My neighbor came over every day to borrow sugar with her baby in her arms, and I thought she was just an unorganized young woman. Until one morning she whispered: “I’m not here for sugar, Mrs. Carmen… I’m here because it’s the only way he lets me leave the apartment alive.”

The months that followed were strange without them. My apartment went back to being silent. There were no more baby bottles on the table or toys rolling under the sofa. At 8:17 in the morning, I would still wake up alone, waiting to hear Lucy’s soft knocks on my door.
