<human>:  How can I tell if a person is lying to me?
<bot>: One way to tell if a person is lying to you is to pay attention to their body language. If they seem nervous or hesitate before answering, or if they shift their gaze away from you, these could be signs that they are not being truthful. Additionally, if their answers don't match the details of their story and their facial expressions don't seem to match what they are saying, it could be a sign that they are not telling the truth.
