Idiots in my class

I think I'm clever. My grade and exam results say I'm clever. I'm in
a gang of girls that are all clever. But, there is another gang of
girls in my class. Issy's gang it's called. They date 14 year olds and
1 of their members has got in trouble with the police. In answer to a
question, they don't even put their hand up. 'I don't know,' they say
when they're asked a question, smiling sweetly, twiddling their
carefully hairstyled hair in their fingers that have fake nails on
them, looking slightly embarassed. We had to work with the person next
to us in English. I've got an idiot next to me. Even though I love
English, I was determined to get the idiot involved. All I got out of
her was, 'I don't know,', 'I don't mind,' and 'You decide.' I get so
stressed. The other children had written a paragraph. We had written a
sentence. I knew I could have written a paragraph. That's why I get so
stressed with idiots. Why can't you even try? Don't you care that
you're an idiot?
