Did you know I left the store with ten items I had pocketed?
Why would you steal from the store?
I paid for the other things, but I didn't want to spend too much money.
it doesn't really matter if you partially paid, it is still theft since you didn't pay for the other things. If you are caught you can get into serious trouble.
I shoplifted for a really really really really good reason.
There is really no good reason to steal anything. If you were able to pay for the other things, I'm sure you'd be able to pay for the things you stole, too.
