Dorm rooms and shared apartments function like small laboratories of adulthood. They are imperfect, crowded and often uncomfortable by design. You learn quickly that no one is coming to enforce bedtime or remind you to eat vegetables. In that absence, habits quietly step in to fill the void. How you wake up, how you respond to mess, how you treat shared space, how you handle tension — these patterns begin to solidify long before you realize they are becoming yours.
