Why Can't They Just Understand???

I am a mostly vegetarian, and my family keeps pressuring me to eat meat. I do not want to eat meat, I do not like most meat. Can't they just understand? Vegetarians are not common among my friends/family, so I get teased quite a bit. It is so frustrating. No one understands. Why can't they all just leave me alone! We had tacos last night, and I said, "No meat, please," and I got meat anyway, and I was forced to eat it. Why can't you just understand people!
