They cool.

Part of it was remembering on a set from Friends. And part of it was promoting the movie, "he's just not that into you."

Part of the conversation had to do with Jen helping to rescue a dog. Well, she and the photo hounds following her helping to stop a dog from getting run over and then finding its owner.

And part of the conversation had to do with Jennifer Aniston turning 40. Yeah, 40 is a hard age to hit. But the good news, or the bad news depending on you look at it, is the next decade and the turning 50 will happen in what feels like one year and by 50 you no longer really give an f about that number. You are only as old as you feel.
