Tell Mrs. Rose the REAL reason.

"Sure," you think to yourself. "They ALL say that."

However, you decide to return the look directly into the Principal's eyes. After doing it for a few seconds, you have the response that you believe that she deserves.

"I'll tell you what," you offer. "I'll tell you what REALLY made me late... If you make some more time for me at the end of the week."

Before she can reply, you grab one of her hands in yours, and place it near the base of your fly.

"If we can make that deal, it's going to be a LONG weekend," you tell her.
