I could hazard some guesses, totally IMO. Her behavior to me that day COULD point to some withdrawal (though not necessarily). She was reportedly nervous, maybe agitated, expressed fear, and left in the middle of her son’s game. She wouldn’t have left just to go to a party. My theory is that work had become too stressful (regardless of whether or not she was skimming). It’s possible she had a falling out with JS the week before, leading to the muffin drop. It’s also entirely possible that if she had developed a habit, that she was feeling it was becoming out of control and she may not have wanted to be alone. All completely JMO, and in no way do I blame her for what might have happened. I recognize some of the behavior as a possible red flag, that’s all.
