Walking to school, Suzie realizes she forgot to complete her homework, so she starts biting the inside of her cheek.
Speaking with her friends before school, Suzie forgets all about the unfinished homework because her friends are distracting her.
As the bell rings for first hour, Suzie thinks to herself, “Nobody did the homework for second hour, I’m not the only one.”
hmm, there's no way that anyone else did the unnecessary homework
In first hour, Suzie pays attention in class, pushing the idea of the unfinished homework to the back of her mind.
During second hour, the teacher collects the homework that was assigned for the weekend and Suzie states that someone must have stolen the completed homework from her backpack in first hour, and reinforces that she did in fact finish it.
I promise I did it
Suzie’s teacher understands that Suzie did not complete the homework and was lying about its whereabouts, so she punishes Suzie with a detention.
