Dear Diary,

    Here I am in the middle of a city, 350 miles far away from our farmhouse. Do you want to know why we move last week? Dad lost his job, and as Mom explained, “He is lucky to find other one.” His new job meant I had to say goodbye to my classmate, my school and just everything else I love in the world. To make things bad, now I have to share a room to my younger sister, Maggie. Tomorrow is first day of school. I am very tiring, but I know I'll never fall asleep.

    Good night or remember, you, dear diary, is my only souvenir of my past life and my only friend.

Yours

Rosemary
