'Pol is 29 and has Down's Syndrome. He's like a little child but in a big clumsy body. Mum complains all the time and says that everyone says Down's syndrome kids are so sweet and gentle, but  her son is the exception, and then she sighs. And it's not just that he's not sweet, he's also cheeky and stubborn and he throws tantrums. And he's a real pain. Because everyone, no matter how intelligent they are, has their virtues and their defects.'
