From a roundtable interview of new fathers at The Morning News:
I remember the first time we took our son on vacation, for instance. We spent our days making sure he was fed on time and always had a clean diaper and got plenty of naps—in other words, pretty much the exact same stuff we would have done at home. After about the third day it finally sunk in that, for the next 18 years, “vacation” just means “go to an exotic locale and still be a full-time parent.”
