Anne, my 2-day-old daughter, will apparently be a persuasive rhetorician. She already understands the value of backing up her claims with evidence and reasoning. Just a few hours after birth, she cried somewhat rather loudly and quite persistently, "Waaaaah!!" (Translation: Change my diaper). "Is it necessary?" I asked. She cried again, "Waaah, waaaah, waaaaaah!" (Translation: If you want evidence, check it out.) I checked it, and yes it was wet. But I still requested reasoning to attend the evidence. She simply looked me in the eye and gave one loud and short burst, "Waah!!!" (Translation: You figure it out!!!) So, her matter-of-factness, and intensity, convinced me to immediately give her a new diaper.
