What is the theme of So B. It?
The theme of so b it is like a nightmare Heidi is forced into employment. Bernette is in charge of the family yet can not go outside because of her A.P causing more stuff for Heidi to do. So B. It/ Mama can not to much more then say 23 words and colour during school time.
