Tap your fingers against your lips and then shake your head as if you're holding in some tiny buzzing words.
Whisper your own promise to be brave just like Charlotte.
Pretend to wave and say 'hello' to your invisible friend, just like Charlotte did.
Giggle and chat with your friends around, just like Charlotte did with hers.
Stand up as straight as you can, put your hand on your heart, and say, 'I'm ready' with a big confident smile.
