Annoying people

I hate it when people are always asking me questions about my diet like "but you used to love..." And "you should really just eat a piece of meat, you are going to get sick without it". I hate the way they put it too! Doesn't "piece of meat" sound so unattractive!! Also people are always like "my parents would never let me become vegan", "you really should just eat some fish", "don't you miss ...?", "I want to become vegan when I am older but I want to grow so I need protein", "you should really rethink your diet", "I think that you're eating habits are unhealthy", "that's crazy", always asking people around them when I am with them "have you ever heard of a tall vegan?" So annoying I wish I could just tell them the facts and they believe me but they don't and never will they just think I'm stupid and crazy and unhealthy.
