" It was the weekend. She was watching a film on TV. It was about four teenage girls, friends who’d been devastated to find that they were all going to have to spend their summer holidays in different parts of the world. So they made a pact that they’d share a pair of jeans, meaning they’d send the jeans by post from one to the next to the next and so on as a sign of their undying friendship. What happened next was that the pair of jeans acted as a magic catalyst to their lives and saw them through lots of learning curves and self-esteem-getting and being in love, parents’ breaking up, someone dying etc. When it got to the part where a child was dying of cancer and the jeans helped one of the girls to cope with this, George, sitting on the floor in the front room, howled out loud like a wolf at its crapness.
