Five years from now, I will still remember how to spot a liar. This topic is really interesting to me, because lying is an unavoidable part of our world; almost everyone has been in a situation where they have lied to someone or vice versa.
There are many situations in which it's really important to tell if someone's lying. For example, if you suspect someone of stealing one of your belongings, you could ask them a question and see if they give off any of the main characteristics of a liar. Some characteristics of liars are: looking up and to the right before responding to a question, continuously shifting their eyes or avoiding eye contact altogether, tapping their fingers, keeping their arms crossed, keeping their hands tightly folded, and sitting at an angle to the person they are talking to. If I remember these characteristics, I will be able to use that knowledge in my everyday life when talking to my coworkers, friends, and family.
