a conversation between 6-year-olds

Kelly overheard a conversation between Madeline and Nathan (our Nephew) that goes as follows:

Nathan "I want to be a bull fighter."
Madeline "You can't, your not suppose to hurt God's creatures."
Nathan "I want to be a bull fighter!"
Madeline "Your not suppose to hurt God's creatures!"
Nathan "You have to kill them to get meat to eat."
Madeline "Why can's we just plant food to eat?"
