My brother's car looks so nice but I am thinking of totaling it.
Do you think that's reasonable to wreck someone's car?
It's the only way he'll take driving lessons seriously.
You shouldn't damage someone's property just to teach them a lesson. Everyone is different and some people just have a hard time learning a lesson.
I'll do it anyway even if you basically said I'm a psycho.
I didn't say you are a psycho, just that you are doing something very bad. Your brother won't learn a lesson here and just think that you are cruel.
