Kissing the phone
I love that scene where Peggy is on the phone with Johnny, trying to tell him that she's pregnant. I'm not sure why she left him in the first place, I think they were fighting but she tells him and you can tell he's apologizing to her on the other end you can really believe him, even though you don't hear him.
This is my favorite part. She starts calling him little lamb and precious. This is what all couples should do when they fight, make up so tenderly afterwards.
Again, I love that she kisses the phone. You can imagine that kiss was ment completely for him. How sweet and sexy. I love that part.
