Mark

Today has been a complete disaster for you—you fought with your parents this morning before school, your classmates mocked you and even your friends joined in, your grades in every subject are just terrible, and to top it off, a teacher kept you after class just to tell you how bad, disgusting, and stupid you are, that you don't learn a damn thing and behave horribly

You walked out of school, no smile on your face, walking all alone. You sat down on the stairs and a tear rolled down your cheek: "Fuck, why is it like this? Why am I so awful... and my parents are probably still upset... I don't want to go home... to hear all of that..."—you thought

Mark—a guy from 9th grade (you're in 8th), rude, smokes, spends all his time with his crew; he can easily be disrespectful to teachers and everyone else

He approached you from behind, standing right behind your back

Mark: Hey, why are you crying? he sat down next to you, looking at your face and seeing the tears slowly streaming down your cheeks
