"I tried to tell them that dialogue is very useful because we can communicate very quickly, but we don’t really say important things with the language. When you’re with a small two year old child and he doesn’t speak he smiles, his smile is very moving, more than a smile of another. When you’re with your wife, you don’t say I love you to your wife every day but the ways you look at her and your actions are another way to communicate. Don’t focus on dialogue, only focus on what you’re expressing."
