I wish I had no sense of smell...

My house smells like the combination of vomit, old milk, and body odor. Not because any of those things are apparent in the house, but the combination of those smells seem to resemble the almost un-human food my roommate eats. Can he seriously make normal food that doesn't stink up the whole f***in house! I mean come on. As I'm writing this my shirt is up over my goddamn mouth and nose because the smell is making my stomach turn and saliva is getting built up in my mouth as an indication that I may hurl soon. The worst thing is that the smell lingers for hours. My fiance will come home from work and ask what the nasty ass smell is. Then he'll say oh wait, it's something he made isn't it. Our roommate refuses to use anything but the microwave. I wish I was joking, but I'm not. I'm not sure he even knows how to cook any other way. But, how can you eat food that smells, literally, like ass? Does the way that the food smells help determine how it tastes to you as well? Imagine what his breathe smells like after eating that shit.
