Follow agreed-upon rules for discussions (e.g., listening to others with care, speaking one at a time about the topics and texts under discussion).

All conversations have "rules," and a lot of 'em seem implicit. But as you've probably experienced, first graders one-up each other better than frat boys and overshare like lovesick teenagers. Such complex human beings, right? Be explicit and lay the rules down first. You'll thank us.
