After the automobile accident, Sam climbs out of bed in his bare feet. Sam walks out of the bedroom and the camera zooms in on Sam's bare feet as he continues down the hall. We see another shot of Sam's bare feet as he ambles down the stairs to the kitchen. Sam's dad, who is on the front porch, sees Sam through the kitchen door and calls out to him. As Sam instantly runs to meet his dad, we clearly hear the sound of Sam's bare feet slapping on the hardwood floor as he races across it. But as he barrels through the kitchen door onto the porch, Sam suddenly and miraculously has his boots on.
