Sharon called about four times today. At least it shows she's trying to explain something to me. I feel a little better.

This morning Sharon said she had only told one person and didn't know why everyone seemed to know. Yes, I am an adopted (收养的) daughter. But she had promised to keep it a secret forever!

I wish I had a friend I could really trust all of the time. I thought I found that friend, but I haven't and it's making me miserable (痛苦的)! It's wrong to tell her all about it. She gains my trust, and then loses it.

I have a nice room, beautiful house and everything I've ever wanted. My adoptive parents will give me all the 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.

Sharon just called. She said she thought it might help if we spent more time together. She worried that I would change schools. 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.

I just had the most fantastic two days of my life! This was the best time I've had for a long, long while. Yesterday, we walked five times around the park and today we walked along the river for twenty minutes. We talked so much. Sharon, Sharon, no brick wall between us now.
