In Rash the mom is the caregiver. She is a caregiver because she cares about her kids and wants to direct them in the correct way. Even if she fails to do so, she still loves her children and family. She is also a caregiver because she follows the rules no matter how crazy and ridiculous they are.
"There are only four kinds of people in the world - Those who have been caregivers, Those who are currently caregivers, Those who will be caregivers, And those who will need caregivers." Rosalyn Carter
