So far, we've seen Louis C.K. interacting with his own daughters on 'Louie' (Thu., 10:30PM ET on FX), but they're young enough that he's still kind of the hero in their life story. It's an easy role to play, and it certainly makes talking with them easier.
This week, he got a sneak peek at the challenges in keeping those lines of communication open as they get older when he tried to talk with his 13-year old niece, Amy. He simply could not get through to her, and it's because he was focusing on talking to the kid in front of him.
