it's ptsd from the vietnam war bruh. cmon man, cut him some slack.
Do you think Big Brother is ever going to admit he's wrong?
No.
Father needs to stop Big Brother.
Immediately.
Big Brother needs to be grounded, and put on permanent restrictions until Big Brother admits he's wrong, and apologizes.
Then, Big Brother may regain very limited priveliges until he can prove he is committed to behaving more responsibly and has made major efforts to positively adjusting his attitude.
If Father sees no improvement, Father will have no choice but to go back to the old methods of discipline.
Big Brother has no idea how men from past generations controlled unruly behavior.
Big Brother, realize the old methods will hurt Father more than it hurts you.
