How, concrete?

Students often ask me for concrete examples for concrete examples. Here’s one from today’s twitter stream: 

Same topic, same conference. Which of the two starts a movie in your mind? 


Well. That was easy. When it comes to understanding/presentations/learning/changes, concrete beats abstract. Always.

When you make me see things, you make me feel things. Even things I may not want to feel.
