It's wrong to be dishonest with school work.
John copied a story that he found online for an overdue creative writing assignment, and was asked by his teacher how he came up with such unique plot.
John wants to answer the teacher's question.
John reluctantly admits to the teacher that he ran out of time, so he copied and pasted that whole story and none of it is his work.
John tells the teacher he leaned on some past memories and experiences to come up with the plot.
The teacher tells John what he did is terrible but that since he was honest she will give him an extension to come up with something original.
The teacher finds out John lied and gives him a failing grade for plagiarism.
