Oh, my...she's been reading the book of MLC quotes (again). She doesn't understand that her actions have created the consequences that she's now facing and yes, the shifting of blame is all too present in their minds. I think you did a very nice job of responding to her. You've given her something to mull over for quite some time.
From Halloween to St. Patrick's Day, the MLCers tend to come out to play a bit more and in some cases, they contact their families more and even want to reconnect for a while. This is when spouses get their hopes up that their MLCers are waking up...I caution all to step lightly, keep your eyes and ears open and those expectations at zero because once the holidays are over and done with, they tend to go back to the way they were acting pre-holidays. Sometimes the holidays will also bring out the worse in them, this too should be looked upon as it's about them and definitely not your problem.
