I don't get it!

So, I'm in college, yet again. Don't get me wrong, I'm diggin the scenery, but I still find I have issues with people. The one that is weighing on me at the moment is people's incessant need to prove that they know more, have more, or are better at things than others. There's a dude in a couple (yes I have to put up with him several times a week) of my classes that has this immensely irritating need to steer the class topic off course to something that would, in his mind, prove he knows more than others! While I'm pretty abreast on the subject matter we are covering, there are things that I could learn or learn how to do more efficiently, hence the reason I attend and pay attention in class. This guy, seems like he might be a pretty decent dude, just continually feels the need to loudly interject a completely irrelevant topic into the discussion. I reckon this wouldn't be all that bad of an action IF, he actually was interjecting reliable and correct content! I don't claim to know everything! Really wouldn't want to, too much responsibility in omniscience! I will own up to the fact that certain topics I do have an extensive knowledge base for or at least enough of one to call bullshit on someone who just seems to need to be the smartest or most knowledgeable one in the room. I tend to only apply what I know to the topic at hand and under direct inquisition. Now I'll help someone out if they ask or it's readily apparent that they are frustrated and need/want help. In my mind, this is how it should be. I feel no need to stand out among the masses, intellectually anyway. I reckon what this all boils down to is it irritates to the point of fucking pissing me off to have to sit in a class that costs money and could reinforce/expand my knowledge base and have to listen to some jackass spout off an unending line of bullshit at a volume well above the generally accepted "inside voice" level.

So, anyway... Just trying to vent away the growing urge to beat the dude about the head and ears with an ax handle! Of course this could just be a waste of a perfectly good ax handle... Hope it doesn't come to finding out!
