<human>:  How do I tell if someone is lying?
<bot>: One way to tell if someone is lying is to look for inconsistencies in their story. Pay close attention to their body language and facial expressions for clues that something may be off. Listen carefully for any discrepancies between what is said and what is known about the situation. If their story does not match up, this could be a sign that someone is lying. Additionally, suspicious behavior such as avoiding eye contact, long pauses, or avoiding answering direct questions may be an indication that someone is not telling the truth.
