on a caught in my office. i have a wife i love and kids i adore. i spend about 1500 plus nights away from my family. and it was sort ofime to reevaluate and recalibrate. sometimes what people say are really the story. sometimes it is a life changing moment and a mid-life decision making. >> the real question is what your tolerance for that kind of life is, and that can change over time. it is a difficult life. i admire people in the congress. i don't disdain them. but you have to make those calculations, some of which are political, about what your level of tolerant for that lifestyle is. >> i don't want to let you go without asking you about iran. there was a lot of confusion, but the letter as written
