Tonight I'm making asparagus (roasted, with garlic, mmmmmm) because C.J. will not be here for dinner. If he was here every single night, I'd get to the point where I said, "Well, tough; the rest of us like asparagus, so you can dig carrots out of the veggie bin or frozen peas out of the freezer or make yourself a salad or whatever." (Anyone who doesn't get their RDA of fruit and veggies in this house is a total hoser and not even trying.) But he doesn't eat here every night, so it's easy enough to make sure asparagus is around when he isn't.
The problem with STSN is that it doesn't actually make me ill, so I don't feel it would be reasonable to ask him not to make it. There are things I will ask him and timprov not to make because the smell of it will put me off food for days. timprov also has a few quirky ones -- my poached pears in white wine, for example, will put him off food indefinitely. (He likes pears. He likes white wine. He likes the spices I put in it. It's just the combination heated on the stove that's problematic.) But we all gross each other out from time to time, just not enough to put in anti-requests.
If you live with people, what do your housemates make that grosses you out? Is it bad enough for you to ask them to eat it when you're not home, or is it just something you flee from personally? If you live on your own (or with people, why not), was there something your parents ate that was truly vile? (seagrit: there is a limit on how many characters can go into these posts, so just pick a few Dave Favorites. :) ) And what about school cafeterias (college or before): what really grossed you out there? The very thought of my grade school's canned peas is enough to make me glad I've already lunched. What's the worst stuff in your food world?
