In the theater there is a substance one can use to bring tears to your eyes. They use it all the time in Hollywood. Jus’ Sayin’!
Agree about the “substance that can bring tears.” I had a lot of speaker training through my professional years. Many of the tricks of techniques are borrowed from showbiz. Shrillary’s schtick if full of this crap — all the smiling and waving. Speaker training will put you in front of a video camera and have you practice smiling to find the best, most pleasing smile. Once the smile is established the trainer forces you to take notice and remember how the facial muscles feel. After that it’s a snap to instantly bring forth “the smile.”
