Isn't that how you learn about what you don't know? By talking to and listening to those who are more knowledgeable than you, smarter than you and kind enough to share what they know? My favorite encounters are with such folks, of whom there are more than a few on Answermug. At least in my little corner of it where I hang out. So do you like to be the smartest and most knowledgeable one in the room or are you like me and prefer to be educated by and learn from those who know more?
