"Filler": Over at School...

Mixy twirled her pencil.

His specs broke again, the second time this week, what happened?

"Uh... Mixy, question 13, the part about..."
"The angle of x is the same as angle z, due to two laws, and angle z is related to the answer by the cosine rule."
"Oh..."
"Split the diagram up if you can't see it."
"Oh ok."

The sound of scribbling on papers filled the room once more. Flicking the pencil over to her left hand, Mixy started writing her notes in uncomprehensible handwriting.

How can he write so smoothly?

"Can you..."
"Question?"
"15a"
"Make sure you do not factorize before you bring over all the variables."
"Oo... Why?"
"That's something Malix spent hours teaching me, I'll show it to you tomorrow."
"Cool, thanks!"

The pencil switched hands once more.

Why does he do all these uneccessary stuff?

Her right hand scribbled furiously on the paper.

"Hey, let's go for a break!"
"I'm for it!"
"Yeah!"
"Ok, let's go." Mixy dropped her pencil onto the table and got up.

A pair of deep, sad eyes were drawn beautifully on the paper.
