Is OTHER wrong in the post ? POST : I'm a 1st year music teacher. I'm in my band class working with the students and one of my trombone players walk in late. He casually sits down in the wrong section and begins looking at someone else's music because he forgot his (he's still in the wrong section so he's reading baritone music. Not even his own part). I look at him and ask him where his music is. He says he left it in his cubby. I am him why and he says he just forgot it. I'm livid because I'm looking at a person who is in the 11th grade and has been in band since 6th grade. I start to chew him out on how he could leave his stuff around on such a regular basis. He tells 9th graders to keep up with HIS stuff. About student includes himself in the conversation of me chewing him out and says that it's just a piece of paper. I have to teach high schoolers the fact that waking into a music classroom is like waking outside without pants on. They still disregard it and say it's just a piece of paper.
