Jennifer considers me like a friend to talk, laugh, and do things with her. She believes that I am a friend she can depend in time of need. I was watering the flowers in the garden this morning when she drops in, telling me that she needed my help because I was in low spirits. When asking what made her so unhappy, Jennifer told me her friend Tina was reading her diary the other days when she entered the classroom. She was too angry at the time that she shouted at her, which, of course, ended their friend. Having heard what she said, I said, "We shall never have friends unless we expect to find them without faults."
