I used to vandalize houses under construction in florida
Why did you vandalize houses under construction?
I was upset when I thought about cutting my depressed brother out of my life.
It is understandable to feel upset with yourself when you considered cutting out your depressed brother out of your life. You wanted to lash out but it was wrong to vandalize other people's property. Plus you broke the law too.
It wasn't a big deal. It's not like I hurt anyone with it.
Even if you didn't hurt somebody, you broke the law. You caused damage that other people would have to fix and that is wrong.
