The document discusses props used in a short film, including two cards. The Biological Father's Card was intended to be given by the protagonist to her biological father but she was unable to give it to him, making the situation more sad. The card represents her inability to let go of him despite having every reason to hate him. The Foster Dad Card is given by the protagonist to her foster father at the end of the film, representing her acceptance of him as her new father figure and increased independence. This final card usage is meant to symbolize the protagonist getting over her biological father's neglect in favor of her foster father's affection.
