Thanks for commenting and asking... Good points. I can remember to add as much back story as possible when I write something..

....What motivates Marsha to enroll in adult education program where she is able to make new friends and engage herself with strangers...

Marsha is socially awkward. Social skills are nill so writing gives her an opportunity to associate with others from a safe distance.

...Why family members behave with her like that she thought them as snacks...

Sometimes not all members of a family are desirable. We don't choose our family members. Sometimes we get stuck with some who are aggressive, hostile, envious , etc .

Yes. It was a great relief for her. She was happy for her uncle but even more happy to not have to go.
