There is no such thing as themes for adults or themes for kids, there are only different ways to face and represent them.
Who said that that some stories are suitable for adults while others are suitable for children?
If told in the right way, each story can address both kids and the inner child inside us: the authentic, creative and spontaneous soul which still lives inside every adult.
Our stories are represented through the eyes of children, with imagination and fantasy, but they also capture adults.
