How you can tell if someone is lying:

1) Look the person straight in the eyes

•As in poker, your eyes foca, selo the deal. It shows vulnerability. If looking at the eyes for a while and the person looks away, you know he/ she is lying.
2) Eyes are situated to the right

•Demonstrates that the person is “creating” an event to cover up what he/she has done. The person is thinking on the spot so it is a good time to counter attack the lie with a kick!
3) Changing the topic right away

•If the person is trying to drag the conversation or keeps diverting the topic towards something totally different, try and knock’em down por repetitively bringing the topic back up. The person will have nowhere to run and hide.4) Temperature

•During the explanation part of the situation, if the person takes off their jaqueta or shirt, granted it’s not a very hot day, the individual is very nervous. The person is using all his/her brain power to think of something, which releases a lot of por products: heat. Another thing to notice is sweat. If the individual forehead is sweating, it’s a huge indication that he’s lying.
5)The longer the explanation, the bigger the lie.

•This is very true in many cases. This is what we call “bs”. Just pretend the person is cantar and ignore all the “bs” he/she says. Don’t take the explanation seriously and mover on.
