‘Hello, children,’ calls Miss Dainty. ‘It’s very nice to see you again.

Are you all ready to dance like butterflies and trolls?’

Billie and Jack look at each other and nod.

‘Now, Billie, perhaps you can follow Lola today? Jack, you can go over with the boys.’

‘Um, actually, we’ve decided to swap parts,’ Billie says.

‘What do you mean?’ Miss Dainty asks.

‘Well, Jack is a much better butterfly than me,’ Billie explains.

‘And I think I am a very good stomping troll!’

Miss Dainty smiles.‘What a marvellous idea!’ she says.

‘Of course you can be a stomping troll, Billie. And Jack, if you would like to be a butterfly, that’s fine with me.’

‘Yay!’ say Billie and Jack together.

Jack flutters around the room and Billie stomps after him. Jack makes a very good floating butterfly and Billie makes an excellent troll. They both have lots of fun.

At the end of the lesson, Jack’s dad is waiting for them at the front door.

‘Well,’ he says, ‘how did dance class go tonight? Still going to be a famous ballerina, Billie?’

‘Maybe,’ says Billie, smiling at Jack. ‘But I think I prefer soccer.’
