At recess, Mika follows Billie to the soccer pitch. They sit down to watch. Jack runs up to them.

‘Hi, Billie,’ he says. ‘Do you want to join our team?’

‘Um…’ Billie isn’t sure. She loves playing soccer but she doesn’t want to leave Mika on her own.

‘Come on,’ pleads Jack. ‘We’re losing. We need you!’

‘Oh, all right,’ says Billie. Then she turns to Mika. ‘You wait here. OK?’

She taps the bench. ‘I am going to play soccer.’ Billie points to the soccer field.

Mika smiles and nods. Then, before Billie can say anything, Mika runs onto the soccer pitch! Billie’s mouth drops open.

What? That’s not what Billie meant! She watches Mika run after the ball. Mika is fast. Very fast! Maybe even faster than Billie.

‘Hey, Mika is good at soccer!’ Jack says. Then he runs onto the pitch too.

Billie plonks back down on the bench and squeezes her mouth tight. She feels a big ball growing inside her. It’s not fair! Billie is the best girl at soccer. Not Mika!

When the bell rings, Billie stomps back to class. Mika follows her.

The next lesson is Art. Mika sits next to Billie. Billie is still feeling cross.

‘OK, class,’ says Ms Walton. ‘Today I’d like you all to draw an imaginary land. I want you all to come up with something unique.’

Hmmm… thinks Billie. Something unique.

Then Billie has an idea. A super-dooper idea. She will draw a polka-dot land. Polka-dot trees, polka-dot houses, even polka-dot people.

No-one else will think of that! thinks Billie. She works hard on her drawing all lesson.

Ms Walton walks over. ‘That’s a wonderful drawing!’ she says from behind Billie.

‘Thanks!’ says Billie, feeling proud. But when she looks up, she sees that Ms Walton is speaking to Mika.

Billie looks over at Mika’s drawing and

Mika has drawn a polka-dot land too. Polka-dot trees, houses – even polka-dot people. Just like Billie!

Billie is That was her idea! She feels like she is going to explode. She stands up and stomps her foot.

‘Stop copying me!’ she shouts at Mika.

Mika looks at Billie. Her eyes grow very wide.

Just then, the bell rings for lunch. Billie runs out of the classroom. She never wants to be a buddy again!
