he's right there seeing him, the person doing the lying isn't able to evaluate that the brother would know that these are his pants. When you're five and you say you're going out to drive your truck around the backyard it's more like a story than a lie, but when you're 15 and you tell very obvious lies like, “I'm not wearing your pants” to the brother and the kid's got the brother's pants on. What happens as kids get older because they're developmentally stuck due to the trauma they are 15 and they're telling five-year-old lies. They tell obvious lies and they don't know that the receiver of the information can assess the quality of whether or not they're telling the truth.

Many kids who've had trauma and are developmentally stuck engage in this specific kind of lying called primary process lying and actually it's the kind of lying that all kids do probably around the ages of four or five.
