How to read a person like a book — Reader discussion

I found 'How to Read a Person Like a Book' to be surprisingly accessible and practical. Nierenberg breaks down complex concepts about body language and facial expressions into clear, actionable advice. What I appreciated most was how the book emphasizes context—understanding that gestures can mean different things depending on the situation. It’s definitely not just a list of signs but a guide to becoming more perceptive overall. Has anyone tried applying these techniques in real conversations, and if so, how did it influence your interactions?

One aspect that stood out to me was the emphasis on empathy and attentiveness in reading others. The book doesn’t just teach you to spot signals; it encourages you to listen more carefully and be genuinely curious about people’s feelings and intentions. I think this approach makes it less about manipulation and more about connection. For anyone working in sales, counseling, or even just daily social life, these insights can be game-changing. What’s one nonverbal cue you found surprisingly revealing after reading this book?
