Simon: They say as a teacher, you'll inevitably make a student cry at some point.
Lily: You can't really MAKE someone cry. You're responsible for what you DO to someone, not their emotional reactions. Like, your emotions are a chaotic amalgamation of all your past traumas, your expectations and desires, the stories you tell yourself, your physiological state, AND what happens to you. You walk around with all that stuff loaded up like a bomb, someone says one little thing, and then BOOM! It all explodes. No one can predict or control the bundle of causes and effects. And the pressure to MAKE someone FEEL BETTER after you've hurt them can get in the way of the actual compassion that would HELP.
