Maybe her mother isn’t hands on with Lisa anymore because she’s minding the sisters kids for past few weeks. Lisa now has to entertain her own kids and without anyone to help she doesn’t know what to do so just stays on the couch and at home. She said yesterday or day before that the mother has just arrived in as she could see the lights of the car so she has to tidy up. I would say the mother is gone and Lisa can’t do anything by herself!! Sure if she went anywhere before the girls were either left with the home with the mother or the mother went with them to help Lisa!! So it’s just suspicious that mother is gone from the home during the day at The same time Lisa and the girls haven’t left it in a week!
