According to an almost 4-year-old:
Me: Gannon, when you grow up and get married, do you want to be a Daddy?
Me: What kinds of things do you need to do to be a good Daddy?
G: ummmmmmmmmmmmmm..........play, sing, ummm......, get married, and kiss my wife.
He's got this one figured out already! Whew...life lesson learned! Haha!
