Here are two letters to George and his replies.

Dear George, I'm fourteen and I'm much shorter for my age. What's worse, I'm very fat. I want to be 55 kg and to be taller and then I can go to the school basketball team and enjoy myself. Can you help me? Bob	Dear George, I'm learning French but I don't get good marks. I don't know why. Sometimes I want to give up, but I know I shouldn't because languages are going to be very important. What should I do? Alice
Dear Bob, Don't worry if you're shorter than your friends. Teenagers grow at different times. It doesn't matter how heavy you are. You are still the same person. Plan your meals with your mum, and she can help you lose weight. Also, try taking more exercise. George	Dear Alice, You're right. You should never give up, and I'm sure that you've made more progress than you think. You can talk to your teacher and ask her what you should do to get a better grade. Talk to your friends who are good at French. Find something that helps you. George
