Dear Diana,

    Yesterday my friend David came round with a new game and asked to play it by my dad's computer. I was a little worried, because my dad used it mainly for his work, and I'm only allowed to use it for my homework. It happened when my dad was out, so we tried out the game. After playing, I took it off the computer. However, when I restarted computer, I found some of my dad's documents miss. Later in the afternoon, my dad used the computer, but couldn't find the document in it. He became very angry, but I dared not to tell him about the game. Now I'm feeling regretful and disturbing. I'm not sure whether a computer's repair shop can get the documents back. Should I tell him the truth, and should I pay to repair it'?. I wish for your advice.

Steve
