When lying, people often give vague or general information and may repeat themselves unnecessarily, while omitting important details.

Liars may subtly change their story over time in small ways, making it difficult to notice the inconsistencies.

Rather than simply telling the truth, some liars may resort to making others look like assholes to cover up their own lies and protect their image.

Watch their body language and voice: A liar may display nervousness, fidgeting, or avoiding eye contact. They may also touch their face or mouth more often than usual. A liar may have a higher-pitched voice, stutter or hesitate, or speak more slowly. They may also use overly formal language or avoid answering questions directly.
