It seemed that Sally was so fed up with her parents that she wanted to get far away from them. But they seem happy about her leaving! Betty because its a good social move for Sally(and something she wanted and didnt get when young) and Don wont have to see her disappointed look at him! It was nice to see Glen and how he saved her. I didnt realize you had to be so tough to survive in those posh private schools!
Once again Pete uncovered a secret life about a co-worker and now he is going to use it. I alsways thought he was going to blackmail Don, but I think he is afraid to.
That crazy idea for a childrn's aspirin commercial with a Rosemary's Baby theme was out there for Peggy! I love how she tells Don what she thinks of him, but Ted will probably end up hurting her.
