It was sometime in college. I can't remember exactly when, but leading up to that I didn't eat anything except chicken and even then not all that much so it wasn't as hard of an adjustment for me as it's been for other people. I hear a lot of people talk about how they try it for a few months and then have to give up.
Haha, same here. Sometimes, I have to remind myself that other people eat meat. Eating meat/fish has become such an absurd thought to me that I automatically think that other people don't eat it either.
How long have you been a vegetarian for? As for me, I can't remember when I decided to be one... Must have been when I was 11 or something. That was 9 years ago :D
