What is an example of symbolism in the short-story, Witness?

The photograph of Silas, Bernice, and their mother that Bernice keeps in the apartment symbolizes hope. For Silas, the photograph showcases their mother's strength and sense of presence. For Bernice, the photograph is her connection to her mother, who in the present does not approve of her marriage to Dove. Bernice brings the photograph to her wedding as a way of having her mother with her, distorting the reality of the situation and leading her further into the past.
