Mitch Abernethy, 15 I tried to teach my 83-year-old grandmother how to use a computer. It was all proceeding successfully until she forgot which button to press to turn the computer on. I then realised that I would be unable to beat the stereotype of technology-illiterate oldies, and gave up. I don't really take note of the day-to-day 'good deeds' that I do, either because there are too many or too few. Hopefully it is the former, but I'm doubtful. Arusha Khan, 17 This is a difficult question. I guess the last thing that qualifies as a 'good deed' was a visit to several orphanages and underprivileged schools on a trip to Kenya. My schoolmates and I played games with the children, handed out gifts and stickers, and spent time getting to know them. I made good friends with a girl my age called Olivia and I was amazed by her great personality, her intelligence and all the things we had in common. The Kenya trip was one of the most enlightening, rewarding and wonderful experiences of my life and I will return to Africa one day soon and give my time to people who really need it.
