I feel bad for your sister for having a brother like you who DOESN'T have the balls to admit that he is a retard who shouldn't drive. If I was your parents I'd hand you a shovel and ask you to start digging a nice 6 foot by 2 foot by 6 foot deep hole then have you carve a head stone and bury you after I ran you over with the Hummer.
You sir are a pathetic example of human life, I hope that your sister finds out what you did and strangles you or in the least breaks your car into little pieces. You make me sick... I hate animals but what you did makes you no better than the filth on the bottom of my shoe.
