People often lie. why? There are several reasons. First, they want to hide somthing from someone. For example, a son doesn’t tell his parents that he’s datinga girl because he doesn’t think they will like her. Instead, he says he’s he’s going out with the guys. Second, people lie because they don’t want to do something. For instance, someone invites you to a party. You think it will be boring, so you say you are busy. Finally, people often lie because they don’t want to tell someone bad news. For example, you have just had a very bad day at work, but you don’t feel like talking about it. So if someone asks you about your day, you just say that everything was fine.
