So she did. She kept at her job. She was a single mom and had to work. She did a little paperwork and bought the kids used textbooks. She would call from work to make sure that her kids were up and studying. Often they were. Often they weren't. She wasn't that involved and her kids were free to do what they wanted.
Is this an OK situation? Note that one of the kids was 15 and so it was technically legal for the kids to be alone in the house all day.
