I saw a small thing of refried beans so I grabbed it.
Why would you take it?
It looked so appetizing!
I understand it looked good to you.  However, you can't just take things that don't belong to you, even if it's because you're hungry.  You need to ask or pay for it!
Well I've never had to ask for food before so I thought it wouldn't be a big deal.
Stealing is never right. What if someone had planned to eat that later for lunch or dinner? Can you imagine how you would feel if the shoe were on the other foot?
