err...I'm a veggie-tarian too, for environmental reasons.
That said, I think I've eaten meat 3 times in the last 6 years: The most recent was from sushi a friend brought at a noisepop show, which had shrimp in it, which I didn't know. I'm also allergic, so that was not fun. One was in Italy, where I didn't realize that I had ordered elk that the owner/manager/waiter had killed himself the day before -- I couldn't really understand him, and the nod and smile thing was a failure. The last was visiting a friend in Switzerland, whose family had made a huge, 5-course meal to celebrate our arrival, all of which had meat except dessert. I wasn't going to be that rude, after they'd spent all day in the kitchen preparing it, even using some of my favorite foods.
