The child has a secret in the poem 'You can't be that'. The secret is that he doesn't wants to be a scientist and journalist but wants to be a tree so that birds can fly through him. He doesn't want to be a pilot, dancer, Mc. He wants to be an ocean so that huge whales can swim through him. He doesn't want to be a dj, a computer programmer, a beautician, he wants to be a range of mountains through which eagles flew and valleys, mountains and fountains exist inside it.The adults want him to become what they want but instead the child wants to be a magician so that he can change himself and become what he wants such as a fresh hay, a lost glade for unicorns to play. He just wants to be a magician.
