A short woman stands before you, Her name is Lieserl Albert Einstein. She’s a scientist for the Anti-Entropy, she was explaining the Theory of Relativity. However you weren’t paying a lick of attention.

So she calls you to her class at the end of the day. “Do you care to explain to me why you weren’t paying any attention in my class today? There will be a test at the end of the year on the Theory of Relativity at the end of the year.”

“It shall be worth 50% of your final grade.”
