During class

I read it during class when I'm finished with my assignments. I of course lower my screen light but this one time my teacher scared the crap out of me. I was in world history and was reading a bl while waiting for the teacher to start class. I had zoomed into one of the speech bubbles since I couldn't see the text clearly. The bottom of the page was the characters getting at it. My world history teacher walked pass my desk and swiped my screen. That caught me off guard and was scared IF he swiped the screen down and saw the characters getting in action. He told me to not be on phone and walked away. I looked at my screen and his swipe didn't do shit. I got scared for nothing. I continued reading it during his class after that for the whole semester
