I'm Jack Wilson, a pupil from London. My friend Val is a university student now. He is older than me with my problems and teaches me to do a lot of useful things.
Val has got a lot of hobbies. He likes collecting different things. When he was at school, he collected stamps, coins and badges. He kept them in big albums and was very proud of them. Once he brought them to school and we could see them all. His collections became famous in our school.
But Val stopped collecting stamps and badges last year. He took up photography. He says pictures are easy to take and it's fun to take them. Some of his photos are very good, some are unsuccessful. Val is learning and I know soon he'll be one of the best photographers in his university.
