Hari works in human resources for a pharmaceutical company. He and his colleagues are giving a presentation on updates to the company's benefits package. Hari's part of the presentation is on ways to save for retirement. He also knows a lot about the new health insurance options because he has been working on a plan to process the paperwork employees will turn in, but his colleague Anne will present that topic.

During the question and answer section, an employee asks what she will need to do if she wants to change health insurance plans. Anne answers because this was her topic in the presentation, but she mistakenly gives the deadline as December 1 rather than November 30.

What should Hari do when he hears this mistake?
