Respuesta :
that she is not dishonest but she probably got up late and had to run then forgot her homework
We can clearly see that Heather often arrives late and does not do her work in a timely manner. This can be seen in passages saying that "she was afraid that she would arrive late again" or the teacher shaking his head and saying "Again?" because she didn't have her homework. We can infer that Heather is not very responsible and likely has problems prioritizing.
