Person1: We used to be really close , but that all changed once she moved to Shanghai . How about your family ? You didn ' t mention to your biological father .
Person2: I don ' t know much about him . He died when I was just a baby . Even though I don ' t have a blood relationship with my step-father and step-brother , I consider them to be my real family .

[Q]: Person1: Hi , long time no see . How have you been ?
Person2: Oh , I've been fine , but I'm having some trouble with my son .
Person1: Tell me all about it .
Person2: Oh , he's 14 and in the past few months , he's become quieter and a bit secretive . He locks himself in his room and I think he's running around with the wrong crowd .
Person1: Oh , I see . What makes you think that ?
Person2: Well , he's become friends with a couple of older boys who are in a band . And one night last weekend , he came home really late , way past his curfew .
Person1: Really ? What happened ?
Person2: He told me that his friend's car broke down and they had to walk home .
Person1: I see what you mean . I understand why you're concerned . Have you tried talking to your son about it ?
Person2: I haven't yet . I just keep hoping it's just a phase he's going through .
Person1: You may be right , but it doesn't hurt to find out more about what's going on in his life .
Person2: You're right . I should talk to him . Sometimes , it's not easy being a parent . Thanks . It helps to get it off my chest . You're always so easy to talk to .
Person1: I don't know about that , but my door is always open . Stop by anytime .
