Reading someone's mind is not a supernatural ability, it is simply a matter of observing and interpreting their body language, tone of voice, and facial expressions. Pay attention to the person's posture, gestures, and eye movements. Try to understand their emotions and feelings by noting changes in their voice, such as the pace and volume, and try to put yourself in their shoes to understand their perspective. Additionally, ask questions and listen actively to their responses, both verbal and nonverbal, to gather more information about their thoughts and feelings. However, it's important to remember that everyone has different thoughts, feelings and perspectives, and it's impossible to know someone's thoughts with absolute certainty.
