While nonverbal communication can provide valuable information about a person's emotions, intentions, and attitudes, it is not always possible to completely "read someone like a book" based solely on nonverbal signals. Nonverbal cues can be ambiguous and open to interpretation, and it is important to consider context, culture, and other factors when attempting to understand their meaning.
