We have now had SS for over a week. He has spoken to his mom once. She told him that he can call her at 10:30 each night. FI has called her and said that SS will not be on the phone that late and will be sleeping.
She hasn't called FI at all to see how things are going.
I know she checked out awhile back. I just don't know how its possible to still be amazed by this woman.
