This brings up a point I almost said before. I believe one of the main causes of trauma isn't necessarily the event itself, but how the people around you and you yourself handled it. You can teach kids resiliency and toughness, which doesn't prevent them from being hurt but does prevent them from allowing the event to KEEP hurting them to a degree. Also, people can convince others to be traumatized by a past event that wasn't that traumatic to begin with. Therapy tends to do that for many.
