<human>: How can I tell if a person is telling the truth or not?
<bot>: The best way to tell if someone is telling the truth is to observe their body language and facial expressions. People who are being honest will typically have relaxed postures, open eyes and a neutral facial expression. If they are lying, these same indicators may be present but in an exaggerated form. Additionally, you can also ask direct questions to get more information about the situation.
