The boys (to play) computer games all morning.

My grandfather is wonderful. He had quite a difficult childhood. He was one of ten children. When he was just fifteen, he leftschool to go to work and help his parents. He had no time to go out with friends. But he did meet my grandmother and fall in love with her! They got married when they were nineteen. After that, my grandfather worked hard, but he was never miserable and had a great sense of humour. When he was thirty, he went back to school and then to university! He became an engineer at thirty-seven. Now he is sixty-five and he's got a wonderful personality. He never asks 'how are things at school?' or 'How many A's did you get today?' We talk about football and films. I hope I'm like him when I'm sixty-five!
