2.Liars avoid using contractions….
撒謊者不愛用縮略語
“I did NOT have sexual intercourse with that woman”. This is an attempt by the liar to be absolutely clear what they mean but it ends up making the story a lot less believable. Stalling tactics are also common. The liar may ask you a question like “where did you get that information?” while they try to back peddle and come up with an explanation for your question.
