My Friends Are Ghosts

Sandra is the perfect child. She goes to bed on time, reminds her parents to take the chicken out of the freezer, and goes to school to see her teacher. After all, her parents are not professionals; they are beginners compared to the moms and dads of other children. That’s why their daughter helps them.
However, with such responsibility, Sandra is the shyest and most timid girl in the world! She is afraid to communicate with her peers, and her classmates in the prestigious school she attends at the insistence of her domineering grandmother laugh at her.
