[M]y favorite ad hominem attack of the week came from a blogger who read my Time essay on children and happiness and wrote: “Dr. Gilbert is a very bitter and misguided man who needs to experience fatherhood before he again attempts to write with authority on the subject.” Yes, it was painful for me to learn that I am bitter and misguided. But it was even more painful to learn that I am not a father. I called my 30 year old son to give him the bad news, and he too was chagrined to find that we are unrelated.
