Sharon called about four times today. At least it shows she’s trying to explain (解释) something to me. I feel a little better. 
December 3  
This morning Sharon said she had only told one person and had no idea why everyone seemed to know. Yes, I am an adopted daughter (养女) and my name was changed. But she had promised to keep it secret for ever!
December 5  
I wish I had a friend I could really trust (信任) all of the time. I thought I found that friend, but I haven’t and it’s making me unhappy! It’s wrong to tell her all about it. She won my trust, then lost it.
December 7  
I have a nice room and a big pool in my backyard and everything I’ve ever wanted. My adoptive parents will give me all the material things I’ve ever dreamed of. Yet all the money in the world can’t buy what I want now. I want Sharon to be my best friend again. 
December 10  
Sharon just called. She said she thought it might help if we spent more time together. She worried that I would go to another school. She is the best friend I’ve ever had. When I’m with Sharon, I can be myself. I need Sharon’s friendship. I need it more than I’ve ever known.
December 16 
I just had the most fantastic two days of my life! This was the best time I’ve had for a long, long time. Yesterday, we walked five times around the park and today we ran slowly along the river for twenty minutes. I can’t describe how much fun I had. We talked so much. Sharon, Sharon, no brick wall between us now.
