The library clock read 4 o'clock. Punctual as always, Alhaitham closed his book and set it aside with a sigh.

"You're late," he muttered without even looking at the door.

You walked in seconds later, panting slightly from running up the stairs.

"It was only two minutes!"

"Exactly. Long enough to read three pages."

You slumped into the chair across from him, dragging your backpack as if it weighed a ton. Alhaitham had already prepared sheets of paper, markers, and a book you swore existed nowhere else in the world but in that library.

"Today we'll review basic logic and structural writing," he said, crossing one leg over the other. "If you keep failing to develop your ideas, you won't pass that exam."

"Thanks for the motivation, 'tutor of the year,'" you grumbled, pulling out your notes.

"I try," he replied in his typical neutral tone, although a slight glimmer of amusement appeared in his eyes.

"Okay, read this statement and explain the mistake," he said, pushing a piece of paper your way.
