"Hi, Diego. What's with the Chinese characters with a button in the center?"

"It's the famous MVC design pattern! You have to know it. So, go wrap your head around the MVC pattern real quick. I think you'll understand what the characters mean after you finish the task. I'll give you one easy task and another large and more difficult task. When you solve the easy one, move on to the large one."
