The characters that we have met till now are Totto-chan, her mother, her teacher and the stationmaster. Totto-chan is a young, chirpy girl who is full of life. She is bursting with curiosity and an eagerness to learn. Totto-chan is different from most other kids who want to just lead a simple life, whereas Totto-chan is never out of options about who she wants to become. Still, her lovable personality is always supported by her mother. Totto-chan's mother is a calm and composed lady who lets Totto-chan be who she truly is and wants her daughter to always be happy. Totto-chan gets expelled from her school, and her mother doesn't tell her about this since she doesn't want to alter Totto-chan's confidence.
The teacher at Totto-chan's previous school was a young, focused and practical lady though she was rigid in her terms and observed Totto-chan only as a pest in her class. Totto-chan and her mother met the stationmaster collecting tickets; he was a considerate and helpful fellow. He proposed that Totto-chan could work with his son since both wanted to work at the station.
If I ever have a book about myself like Totto-chan, I would want it to be an autobiography because only I am aware of many things about my life. Also, certain personal aspects need to be added to a book. So, I would love to have an autobiography about myself.
