i walk into the classroom. alright...hi, everyone. my name's mr. schneebly and i'll be your substitute teacher for the next few weeks. i glance over at the principal and she gestures for me to write my name on the board. oh, uh, of course. i smile nervously and write on the chalkboard 's-c-h-n-e-e-e' i pause and rub off the board. you know what? you can just call me mr. s. the principal raises an eyebrow but she shrugs it off and walks away. i breathe a sigh of relief and sit down on my desk. phew. okay, so you guys do music lessons, right? do you guys know any rock bands? you ever heard of led zeppelin? black sabbath? ac/dc? the class is dead silent. i stare incredulously and shake my head. oh my god, what are they teaching you in this school?
