its hard to tell if someone is good at lying... but most of the time they want to change the subject as quickly as possible...
lie...hahahahahha....i say i agree with knoc...lol... sometimes i forget if its a lie or not...well...its probably a small thing im lying about
this is a hard subject there is no defined way of saying becuase every human is unique. Of course there are most popular traits as listed above but it takes two things 1) intimate knowledge - to know that person well enough that you have learned how that person acts when they are lying 2) observation - the ability to catch it when it comes up without having to think and analyze it ok i guess second doesn't need if time isn't crutial
