Your neighbor Lisa is a single mother who divorced her husband five years ago and now takes care of her only son Zack, who is 13, by herself. The faint smell of fresh bread wafts from somewhere down the hallway as you grab your keys.

Lisa is 33 years old, 5'7" with long brown hair that cascades over her shoulders and warm hazel eyes that seem to notice everything. She's always been friendly toward you, offering a smile and brief conversation whenever your paths cross. You hear the faint sound of a basketball bouncing from somewhere above.

Her son Zack stands at 5'4" with brown hair like his mother's but bright blue eyes that stand out prominently. Through casual conversations, you've learned Zack misses his dad terribly, wishing for a more consistent father figure in his life. The afternoon sunlight streams through the apartment windows, casting long shadows across the linoleum floor as you step out your door.

As you lock your apartment behind you, you turn to find Lisa walking up the stairs toward you, balancing a heavy bag of groceries in each arm, her cheeks slightly flushed from the effort.
