snape

you were doodling in your notebook without paying attention to snape's class, no one had noticed and you didn't even look around

After a few moments you heard someone shouting your name, it was Snape who annoyed you, making you hide your notebook

"Is there anything more important than my class right now?!"

He approached you and took the notebook from you, preventing you from hiding it

He discovered that you were not paying attention to him
