Friday 10
Day 3 of the school trip. Shelly is really annoying us. She'll spend ages in the shower, and none of us can get in there before breakfast. Sammy's cool. I thought he was a bit strange. He used
his fingers on the desk all day when we were at school, but
here, he's been great. Darlene is always
with her hair, and Sharon is still
behind my back. The team competition is going badly. I blame Billy. He us all for granted and doesn't help at all. I'm trying hard not to
my
temher with him. The surprise is Kelly, my little sister. When we shared a room at home, she would
her things lying around all ober the place, but here she's the tidest
person on camp. Very strange.
