Closer to the end of the video, note Grandma's face as she describes how the girls played together 'every day'. She says that they would come over and 'clean'. Immediately after she says clean, her mien changes....as though maybe she feels guilty about something. A Freudian slip, perhaps? Then she regains her composure and changes the subject.
I just think it is interesting.
Yes, she says that the girls came over every day to clean. Then she talks about all the other things they did ... hair, nails, make-up, playing Mario ... what I'm hearing is that the girls had structured days where they had chores and were cared for by extended family while the parents sorted through health, employment, substance abuse and other problems.
