Flew From Earth

Erwin is playing with his pencil during his English Class. He really hates English as he can't speak it fluently like others can. In addition, his teacher is super strict too. He barely can even survive if he didn't finished his homework. And--

"Hey, Erwin! Are you listening to me right now?" the teacher asks him with a loud voice. Erwin get shock for a second. He answers the teacher immediately.

"Ye- Yes, Sir David! I'm listening," he's so nervous everytime he got called by him.

"Oh, really? Then, how about you solve the third question, right now! Or I will minus your merit," he continues to speaks as he crosses his hands and smirks.

"Su- Sure! That's an easy one!" he stands up and rapidly goes to the board. He's too anxious to even look at the question. He then take the markerpen on Sir David's table and opens the top. He tries to answer it as good as he can even though he really don't know what his teacher even though just now.

He reads the instructions.

"Answer the questions below. Number three. Find the 'x'. 25x + 5 equals to---," Erwin raises his eyebrow. WAIT A SECOND!

He looks carefully at the question. It's a MATH algebra question. He turns his head and looks at his teacher.

"Well, looks like your mind really flew away from the earth. NOW IS MATHEMATIC PERIOD! How long did you sleep in my class, huh?! And you can't even remember your math teacher's name, huh?! I'm Mr. Will! Not Sir David!" he shouts in front of Erwin's face as his saliva 'fly away'.

Now Erwin knows. This time, he really messed up even worse than the 'birthday accident'.
