The main research question in this article is directed to how children use symbols to build up metaphors and through these metaphors express their messages about their culture and everyday life. In the article, I describe how a child, Oskar, takes hold of the power to be the one defining children's own lives by challenging adult's prejudices towards children's computer activities. He does so by making use of metaphors in his digital story. Metaphors are discussed as expressions for discourse and as a way of creating prerequisites of understanding and intersubjectivity. Questions about the making of meaning and identity are also highlighted. Finally, in concert with Mikhail Bakhtin and Paul Ricoeur, the potential of change promoted by understanding and sudden insight as a result of interpretations of metaphors is argued for.
