I think I stole someone's breakfast.
What made you decide to steal someone's breakfast?
I was hungry and it looked good, so I ate it.
No matter how hungry you were there's no excuse for taking someone else's food. Don't take things that don't belong to you.
Ok, I didn't know. I'll take it next time.
It's not very nice to steal someone's food. They must have been so disappointed to realize their breakfast was gone. You should get up earlier and make or buy your own.
