Hit and Run

So leaving work yesterday, I'm pulling out of the parking garage, and round the corner, maybe going 2 mph if that, and some guy whips around the corner so fast and completely runs into me. I slam on the breaks before he hits me and honk like he wasn't even looking and he still slams into me. Oh but the best part is, after he looks up at me, he reverses the car and peels our of the garage. He goes out of his way driving over the curb and out the wrong direction exit to get away. I'm honking and trying to memorize his plate and just watching him speed out of there. Classy guy. So I'm so shaken when I call Greg cuz I don't know what to do, I'm a crying mess. He tells me to call the police so I pull around the front of my work and call them. I'm on the phone with them and walking around my car with the security guard for about 15 mins and the guy that hit me, pulls around the corner up behind my car. He gets out and I AM PISSED. I'm all, "Hey you decided to come back??" And he actually has attitude and just holds up his insurance card in my face. He's like, "I had to go get this". Really guy? That's all he says. Wow. Not five minutes later the cop shows up. I tell her everything that happened and how he drove off. His only response is, "I didn't realize I hit her." The cop just laughs and says sure, i just bet. What a jerk this guy. After everything he changed his story like 3 times while sitting there. From, I didn't realize I hit her, to my friend say the front of my car and said maybe I should go back. Geez. Love some of the people in this world. So, as it turns out, in Texas even if at first the other car hits then runs, as long as they eventually come back to exchange info, it's not a felony so the copy couldn't assign fault or even arrest him for anything. She took down notes but said now it's up to the insurance companies to assign fault. SO help me if they come back with even a single ounce of blame on my end....I"m gonnna lose it. Still so angry about it. Our car's not as bad as his, it could have been a lot worse been the fact he hit, then left, only to return with such and attitude is why I'm still so angry. Geez.
