I know it's a christian book and forgiveness is encouraged but let's be practical.
Whether you're a believer or secular, I say this pragmatically: Callie Brockman was severely overstepping here.
And she was hypocritical, she lectured Rhett on rude Brandon yet she won't give her brother the time of day!
Yeah, I just can't relate to angsty teenagers who commit crimes for dumb reasons. Brandon came off as especially bratty and low key wanting to control his father rather than the other way around. Stealing was still a crime, and even teenagers need proper discipline. If you go too easy you might as well just tell your own child that it's okay to steal up to $900 worth of stuff because nothing will happen to them if they do.
Stealing an item to emulate someone is not worthwhile excuse.
