He sank down onto the couch, the cushions still bearing the slight indent of his father's body. He could almost feel his father's presence beside him. He felt the phantom of his father's arm around his shoulder.

He blinked hard, a strange pressure building behind his eyes. He realized the weight on his chest wasn't from the food, but something much deeper.
