On stealing and peanut butter...

While driving home, the topic of stealing comes up. Carl uses the opportunity to try and teach Julia about stealing and what isn't stealing...
Carl: "So Julia, what if you are in someone's house and you take something without asking...."
Julia: "Like peanut butter?"
Carl: "Uhm, yea sure...Is that stealing?"
Julia: "Yes."
Carl: "now what if you're in a forest..."
Julia: "what if you take peanut butter from the fridge? is that stealing?"
Carl: "If you didn't ask yes....now if you were in the..."
Julia: "What if you take the peanut butter from the fridge to make a sandwich and didn't ask."
Carl: "Yes, now forget about the peanut butter..."
Julia: "what if you take the peanut butter from the fridge, didn't ask and tried to open it but couldn't and put it back in the fridge?"
Carl: "Forget about the peanut butter!!!"
Me: "Wait a minute, Julia did you try to open the peanut butter from the fridge?"
Julia: "No. Never, mommy. I never steal peanut butter and jelly from the fridge! It's too hard to open."
