Eventually..
But, to date, both my boys have never said anything unforgivable and I hope that they won’t (mid/late teens now).
I have always made it clear that I am not a walking wallet and chauffeur combination and I deserve and expect to be treated with respect.
However (and I know I have repeated this on many teenage threads), I don’t understand why people have such reverence for teens and give them so much privilege with so little consequence.
If either of my teens was inexcusably rude to me or behaved appallingly, they would lose both a chunk of money and screen time. There wouldn’t be no negotiation or consideration as to whether it was their ‘teen brain’.
As a teacher (albeit in ‘nice’ private schools), I can see that teens respond to incentives just the way adults do, both positive incentives and negative ones, paired with discussion and reasonable negotiation.
I will never forget a thread on here where a teen was keeping their mother up all night talking loudly on their phone and they were advised by many posters to buy earplugs!
To answer the question, if they said something awful, there would be huge consequences, but they would eventually be forgiven. I can’t imagine never forgiving them.
