"This feels... right," Maria said, softly, as she stepped into the family home. The house was exactly as she remembered it: cozy and filled with the scent of her mother's baking.

Maria laughed, feeling a ripple of delight run through her. "Yes, Mom, I'm starving!" The thought of eating with her family filled her with such peace. She could see herself making it work.
