Ugh. I just had this conversation with my 11-year-old sister.
Her: It sucks that you have to make your own lunch.
Me: It doesn't matter to me.
Her: *takes container of cooked ground beef out of the fridge*
Me: *doesn't comment on it*
Her: Mmmm, this is sooooo good. *opens mouth and chews the meat* I bet you want someeee.
Me: No, it's disgusting.
Her: You're so stupid.
Me: Why, because I don't want to eat the flesh off of an animal?
Her: Yes, that's what cows are made for.
Me: Who's to say that's what they're made for?
Her: What else are they for?
Me: If you read anything online about it, you'd chose to stop eating meat.
Her: So that's why I'm not going to read anything.
Me: So you want to be ignorant?
Her: Yep. And by the way, you're not a vegetarian if you drink milk.
Me: *gives up*
