     Jason

     What I like best is seeing Arsenal win and playing football. If I am feeling sad I will play a football game

on my Play Station 2. The best day I have ever had was when I finished first in the 800-metre race at my

secondary school. It was a school record, although I didn't know that at the time. My family makes me happy,

too.

     Antonio

     My little sister makes me sad because she always tells tales on me to my mum. If I am having a bad day,

food cheers me up. I like chili con came and sweet chili crisps. It makes me happy because I want to be big

and have lots of energy.

     Usman

     I haven't done anything very exciting in my life but one of my best achievements is that I got a good report

from my school this year, because last year I got a bad one. People on TV make me laugh, particularly Eddie

Murphy. If I am having a bad day I watch Basil Brush. I am good at making other people happy. I just talk and

my friends start laughing-they think I am silly.

     Ashleigh

     If I'm having a bad day, knowing that someone is there for me can make me happy. I wouldn't say I'm the

best at making other people happy, but I know that just being a good friend to other people is important. The

things I like doing are singing, dancing, hanging out with my friends and just being lively and funny.

     Kinzey

     The most exciting thing I have ever done in my life was when I went abseiling in Wales. But that was a one-

off. The things I do all the time are playing football, watching movies and going to places with my friends. I

know it sounds bad, but what I find funny is when people hurt themselves. If I am having a bad day I see

someone having a worse day than me, which makes me feel better.
