"I think Snape is watching you"

your best friends fred and george said to you giggling, as you were sucking a lollipop in class

"as if i believe you two" you said rolling your eyes at them, continue sucking on that. even if, you were curious. during the lesson you tried to see if that was actually true and it was; snape was indeed watching you.

as the class ended and you were about to go away you heard his firm voice

detention for you, miss.
