Instead, your whole approach to the conversation should be through question-asking. Rather than making accusations, try to ask him or her questions about their behavior. Specifically, you want to begin by asking them questions that get them to state the relevant evaluative standard. Whether the person was being hypocritical about environmental behaviors, social kindness, a religious belief, whatever, you want them to self-express what they think is the “right” stance to hold on the topic. In other words, you want them to acknowledge their evaluative standard.
