Suddenly their car hit with another one, the owners are a couple. The man is very tall and tough, with also a really aggressive altitude. The woman he didn't mention a lot, but the samilar with the man. Their car was expensive. They insulted his mother and pulled her down on the street. Lorenzo tried to do something but he couldn't. He felt angry and wanted to " kill this man", but with guilty also because he can't react with this thing. He couldn't get out of the car, and also afraid of the man. In his younger memory, he doesn't have that much self-confidence with him. Also based on his willing to be more muture, he pretended he's like a real man.
