What did the note say that Pheobe's mother left for her dad?

Mrs. Winterbottom’s note to her husband simply stated, “I had to go away. I can’t explain. I’ll call you in a few days.” There was no warning that she was leaving, and so Mr. Winterbottom is totally confused. She also left a note to each of her daughters, mostly directions about being safe and what to cook for dinner. Her life before she left seemed to be one devoted to her family. She did the traditional things like clean the house, cook the food, and run errands for everyone else. She seemed to have no life of her own or any desire to have one. Her personality seems to have been squashed by the people in her family, who are unappreciative of anything she does. They just assume that she is there to serve them. Phoebe’s affection seems to be centered more on her father, who she thinks is perfect. Sal has seen this, and so is not as confused as the Winterbottom family.
