Joan was so happy that she drank two bottles of wine with her boyfriend.When it was time to go home, both Joan and Donald were too drunk to drive.They knew it clearly that both of them couldn't drive home safely after that much wine, so they sat in the back seat and asked Mike, Joan's 13-year-old son, to drive the 2008 Land Rover. Being a driver for the first time in his life, Mike could receive no help from his mom or Donald.They were too drunk to tell him clearly what to do. He started the car nervously, but when he realized he couldn't control the car at all, he was scared and depressed. He decided to stop the car and refuse to drive any further.
