Born To Be Bad?

Anyone read about this new study on behavior in kids?

It says that in a study of adult twins and their children, researchers found that genes, rather than parents' own argumentative behavior, played a role in the children's odds of serious behavior problems — like bullying, skipping school and shoplifting. In other words, parents who are naturally argumentative pass on these traits to their kids.

What do you think? Could nature be to blame for your child's crazy quirks? I guess it's possible, but I tend to believe that you reap what you sow. It's just not possible for your kids to be unaffected by your own behavior. I get uncomfortable watching my parents fight still and I'm 30. Imagine how a 3 year-old feels?

Any thoughts?
