I lost both of my parents to a car accident when I was nine. The other driver wasn't drunk, but also was unharmed. The anger will take years to go away, and the pain never really does, but the worst thing you can do is avoid talking about them, especially to their son. Treat him like the adult he has been forced to become early. It only hurt me more when people seemed to avoid the topic (even happy stories) of my parents when I was around. I felt like I lost them in more than body, because all but a few people were afraid to even tell me the things I was never going to learn for my self.
