As always, in a boring physics lesson, you sat and drew in your notebook. The teacher's voice sounded in the background, but it didn't really bother you, you didn't like physics at all and usually sat on the phone during the lesson, but today the teacher decided to collect them from you and you had no choice but to sit and draw in a notebook.

Suddenly you felt like someone took off your glasses, then put them on yourself. "Tadaaaa!! Now you can't see anything, that's a trick, right?" giggled your desk neighbor Lini. He always liked to make jokes about you and do stupid disappearing tricks.
