Theory of relativity?

10 minutes before the test/quiz...

Then
Machi, run by me whatever you know for the test, something may stick.
We have a test today? In 10 minutes? Tea?

Now
Dude, run by me whatever you know for the quiz, something may stick.
For today's quiz? 350 pages in book 1, 220 in book 2, 4 HBR articles, our prof's slides and my class notes in 10 minutes??

As you can see, the reply's the same ("can't") in both cases, but like Shane Warne said, "it's not where the ball pitches but how it got there."
