Is AUTHOR wrong in the post ? POST : So I am a senior in college taking a BS class because I need four  more credit hours to graduate. The class is mostly full of freshman or seniors doing the same thing I am. It is taught by this very kind woman in her 50's who really loves the subject she teaches and loves teaching and working with others. This shows in everything she does and even though I'm taking this class for the credits and its not in my major or a requirement to graduate I find myself respecting her immensely for her passion. 

Enter this one freshman guy. We will call him X. Day one of the class I go to the bathroom during break and I hear X talking to his buddy. They are planning on getting high before class. At the time I think whatever not my business he passes or fails on his own merit. Fortunately, X has very poor attendance even though the class is in the middle of the day and very easy to make it to especially because he lives on campus like half a mile away or less. This all suddenly changes though. As I believe X does sports, not entirely sure he doesn't appear very athletic, however sports require a minimum GPA. I believe half way through the class X realized that attendance is graded or the teacher had a word with him about it. Most likely the latter. 

Now X is attending class everyday and he is coming in high as fuck. Like just getting up and wandering around the classroom cursing randomly or in conversation with the teacher and just making a complete fool of himself. A lot of his freshy buddies find his antics hilarious. I usually wouldn't give a fuck but, I can't help but empathize with the teacher. This is something she cares greatly about and this guy is showing up high literally everyday, not paying attention, randomly lying across the desks or on the ground, and just being a complete fucking idiot. She's tried to hint at him that he should change his behavior but, clearly it's not getting through.

I'm really tempted to call him out on it if he keeps it up or try to find some way to get him in deep shit for his behavior. But, on the other hand I'm a senior so I could hypothetically keep my head down and just not have to deal with him ever again. If I decided to call him out would I be the asshole?
