Coral sees a sort of reincarnation of her dead son in Tom and starts to get closure on her sons death.
At the end of "Away" Coral is doing a play where she plays a mermaid who has her tail changed into legs, She says "I"m walking" in a fake American voice she had been using during the play, but then she starts to say "I"m walking" in her own voice symbolising that she has changed. In the last scene of the play Coral has a hat filled with seashells and gives them to Roy who kisses her hand with the shells in it to show that he is reaffirming his love for her.
Another example of change in the story is Gwen. Gwen is somebody who likes to be in control and has "a plan" that she sacrifices everything to keep her plan. She treats her family as inferior and her husband Jim takes it because he knows that she means well, but Meg doesn't like being treated that way and realises that she means well but doesn't see the point of having a plan if everyone is unhappy.
At the beach Gwen says what she thinks of people who don't try to make their lives better and how she cant understand how people can be happy living like that, after realising what she had just said she discovers that she is a snob and that there are more important things that being rich.
In "The Door" by Miroslav Holub, this is a poem that encourages the reader to change. Holub uses repetition of the words "Go and open the door" to persuade the reader to try it. He gives examples like "maybe outside there's a tree or a wood" and " a garden or a magic city" to represent the good aspects of change. He uses "maybe a dog rummaging", "maybe you"ll see a face or an eye", and "or the picture of a picture" to show the mundane things. Holub also shows the dark side of change as "the darkness ticking" and "the Hollow Wind". He concludes the poem by saying "at least there will be a draught" meaning at least there will be a change and something different.
