I used to steal parts from my neighbors dirt bike to put on my own
What made you think stealing those was okay?
Because I saw others do it.
Just because other people were doing it too doesn't make it okay.  You shouldn't be taking stuff that isn't yours, especially from a neighbor.  I hope you grew out of behavior like that!
It's okay. Pretend we never had this conversation and forget about it.
I can't just forget about it. Stealing is wrong. Don't you think they needed the parts for their dirtbike as much as you did?
