A child finds a stone, touches it, looks at it and starts talking to it.
The stone seems not to listen, but eventually breaks the silence. As if in a dance, question after question, the two draw closer together. At the beginning the stone answers slowly and with few words, but then it talks about life and friendship.
Knowing someone is not enough to be a friend... caring for the other can be difficult, if you don't know what needs to be done.
