Why is it so quiet??

Yesterday I was doing something in the kitchen, and I discovered that it was suddenly very quiet in the next room. Hannah had been playing with her baby ("Anne"), and she was doing so well feeding, burping & rocking her. The next thing I know, Hannah comes into the kitchen with a kleenex and is blowing her nose (very cute, I must say.) The thought that occurred to me was: "Where did she get that??" Hoping it wasn't from the garbage, I went in the living room to find out...
