A woman sits on the ground at Bab Diwan, with a bottle of water and a few of her belongings in a plastic bag. There's a worried look in her eyes, bordering on desperation. Where she sits - one of the fort entrances into the medina - is a busy place. Yet no one walks near her or acknowledges her. She does not approach anyone. She keeps her distance, and so does everyone else. She's alone in her own world, with her own worries and her troubles.
