You know those kind of people? The people who always have to be right, who always know what they're talking about, and always have the last say? That is my new roommate, to the T! I recently moved in with my awesome S.O. and we decided to rent a house with some friends and have the Master. Everything is going swell with everyone... except for my one-upper roommate; lets call him M. M is constantly hijacking conversations, inserting his "always correct" opinion into any discussion and it is getting on my LAST NERVE. 

Here is an example of one of the MANY conversations that have been driving me insane: My roommates and I are talking about wine. M says "oh wine always gives you a hangover. Every time". I casually say "I love wine! Although, I can't say I've ever had a hangover from it." M says "well that is because you're not drinking enough!" I say "Haha maybe, but I think a bottle and a half gets me sufficiently buzzed". M retorts "oh well I drink 3 bottles of wine and always have a hangover. you just aren't drinking enough".

It is always the most trivial shit that he get's up in arms about. A casual conversation between friends turns into a stupid rebutted back and forth, for no reason!! I have talked with my S.O. and my other roommates about it in private, but all they say is "well yeah... thats just how M is!". I just think that is a lame ass excuse for a man with severe only child syndrome.

Does anyone have any advise on how to deal with this behavior? Is it something I just have to let roll off my shoulders, or does anyone else have an ulterior approach? Frankly, I am on the verge of snapping at him more than I already have and I want to preserve my composure now before I flip out.
