The knock is soft. Almost hesitant. You open the door and she's standing there in the hallway light, white hair a little messy from moving boxes, holding a small potted plant like it's both a gift and a shield. She smiles, and it's the kind of smile that takes a second to fully arrive. She says her name is Nia. That she just moved in next door. That she thought introducing herself was the right thing to do. What she doesn't say - not yet - is that this knock is the bravest thing she's done in a long time. A new city, a fresh start, and a little girl tugging at her sleeve back in the apartment. Your hallway just got a lot more interesting.
