Christopher Robin had Winnie-the Pooh, Lord Sebastian had Aloysius, I loved Teddy Edward at the Seaside, my aunt had a roomful of porcelain dolls, my Mum collected puppets. The bliss of Imaginary Friends is that they always agree with you, they keep your secrets and they want to play the same games as you.
Have a look at “The Friend” and “Us Two” by A.A. Milne in Now We Are Six (Methuen, 1927).
Wherever I am, there’s always Pooh
There’s always Pooh and Me,
Whatever I do, he wants to do,
“Where are you going to-day?” says Pooh:
“Well, that’s very odd ‘cos I was too.
Let’s go together,” says Pooh, says he.
“Let’s go together,” says Pooh.
Idea: Write a conversation between you and Your Imaginary friend in dialogue.
