Cuteness is nature's defense mechanism against parents
So the boy asks for something that is entirely out of the question and my wife says, in a teasing way, “Ummmm… I thiiiinnnnk… mmmmmm… no.” To which he immediately responds, “Ummmm… I thiiiinnnnk… mmmmmm… yes!”
And suddenly I realize why two year olds are so cute. If a snotty teenager had done that, it might have been, well, snotty. But the cute factor made this response completely adorable… and his life was spared. I’m certain this is a factor among animals who sometimes consume their own offspring — their babies just aren’t cute enough.
