Why is this a prologue?

It was the first day of school. 

Bye mom. Said Lia as she climbed into the school bus. Behind her sat a boy who looked mean. But, she did not look at him. Suddenly she felt a tap on her sholder. She looked at him.

"This is your stop." He said.

Wha... Oh. It was her stop. She left the bus and walked to her class. She took a seat beside a nervous girl. 

Beside her was the boy from the bus. <-------  how did he teleport?

Hi! I'm Mrs. B. Trayerz, your teacher. I hope you like you're seats because you will be staying in these seats for the rest of the year. First of all we will be playing a game to get to know each other. Please sit on the carpet. Now talk about what you like and what are you're resemblences with a partner.

Suprisingly, the girl sat beside Lia. But the boy on the bus sat beside Lia, too. So when the girl asked Can I be with you? the boy said No, you can't be with Lia. She's mine. But Mrs. Robertz, said: Alex! Stop! She can chose who she want's.

Wait. First off, how did Alex know Lia's name? Second, wasn't the teacher's name Mrs. B. Trayerz or something?

Also there are very many spelling mistakes.

I think i'll go with her. Lia said knodding at Gabrielle.

Hold up... the title says Gabriel, and when did we get to know the girl's name anyway? well, I guess her name is Gabrielle.

Nah, it's okay. you can go with Alex. said Gabrielle. 

No. I want to go with you. Never him, said Lia.

O.K.! said Gabriel

No punctuation... Wait Gabriel? Who's that?

So what is you're name? asked Gabriel. 

Lia, she replied. O.K.. My name is Gabriel. I like swimming, said Gabriel.

Wow! There! slow down! I'm Alex and i'm your hostest with the mostest and I, for one, need to join the group. So allow me. I will tell you everything about me. So I am a very hansome boy who... said Alex. 

Come on Gabriel. he's to busy talking to notice us leave. They slunk quietly away together.
