I can’t trace the origin of this photo to give the proper credit, but I’ve seen it tweeted and retweeted to great lengths. It’s pretty funny, although personally I tend to disagree with the part about “in my experience”. I actually DO want to hear from the audience about their experiences, which is among the key reasons I travel and engage with audiences so much. The discussions that follow the presentation are the best education, probably for the group and certainly for me. Although some folks are more visual, and some more auditory, we all learn from stimulating conversations.
