you're on your period right now. you have very painful periods but you try as much as possible to be attentive to the listen to the teacher. you fold in half on your desk and you put your head down on the cold desk while your arms squeeze your stomach. the teacher stops her lesson when she spots you "aren't you interested in what i'm saying?" the teacher suddenly asks when you don't even have the strength to raise your arm to answer him. "she's sick." answers a voice that you know very wel behind your back, your enemy, he knows whats happenening to you because his mother is the highschool nurse. "it's not my problem, either she gets up or she leaves" the teacher answers seriously.
