Forgive me for saying this, I mean no disrespect for your dad. Listen, I believe you weren't speeding. Rainy roads are slippery and cars can hydroplane. it happened to me. They needed the jaws of life to get me out of the car, but I didn't have a scratch on me. Of course I learned from the experience. Maybe, I wasn't as careful as I should have been..who knows? It happens so fast, you don't remember. I couldn't drive for months afterwards. My dad gave me the encouragement to get back behind the wheel. He helped me buy a new car. I can still remember my parents' faces when they saw me standing there: concern, pity. It's just a car. A piece of metal with glass. Of course it costs money to replace it, but you aren't replaceable!!!! I think your dad is being too hard on you.And as far as the jerk at work, just ignore him. There's no way you're going to convince the idiot you weren't speeding. Is it worth the aggravation? Nope. By arguing with him, you're second guessing the circumstances again. Don't bring it up to him and if he does, just tell him: "Look pisshead (sorry) it's done, it's over, I'm going on with my life" and walk away. Please ignore the guilt trip. Accidents happen and you weren't hurt. Be gentle with yourself. It's over. I know it's hard to get rid of the memory of it, but chalk it up to an awful experience that won't hopefully happen again.
