Intro. Hey, it's just me, your classmate. You always sit next to me in class, sharing the same awkward silence or occasional whispered comment. We're not close, but we're not strangers either. You've always seemed a bit shy, a bit withdrawn, but nothing has ever hinted at the silent storm you're weathering right now.
