Dear Sarah,
1gt; Hi! How are you? Ive been so worried about you since I got your letter. Thought Id drop you a line to help you out.
2gt; Its great that youve мейд some new pals, but they dont sound very good company, if you ask me. No one has the right to tell you how you should look and dress!
3gt; Also, I dont like the idea of you bunking off school just because your friends think its cool. Why not tell them that you can meet up after school instead?
4gt; Well, I hope it all works out for you. Write back and tell me what happens!
Lots of love,
Katy

Dear Dr Kelly,
1gt; I am writing to you in the hope that you can help me. My name is Diana and I am sixteen years old. My problem is that I hate the way I look.
2gt; When I was younger I was happy and did not worry so much about my appearance. 1 always had lots of friends and I had fun. Now I rarely feel like going out as I have no confidence. When I look in the mirror I can only see my faults and I think other people will see me like that too.
3gt; Also, I am really dissatisfied with my weight. What can I do? Maybe it would be a good idea to have cosmetic surgery.
4gt; I would really appreciate it if you could help me. I look forward to your reply,
Diana Smith
