W: Hey, Jimmy, a couple of us are going out to Sam’s Bar after work. Care to join us?
M: Oh, urn.. .Thanks for the invitation, but I’m pretty tired.
W: Well, how about joining the company picnic next Saturday? We will play beach volleyball and you can join our team! Come on! It’ll be fun!
M: Um.. .You’re so kind, (19)but I’m really not sure if I’ll be able to make it. I’m just a bit shy. Plus, I really don’t like loud bars or clubs.
W: Let me tell you a secret. I hate bars and clubs too! But, I know that going out and being seen is a big part of social networking. (20)Social networking means going out and meeting people. It really can mean the difference between success and being stuck at a dead-end career.
M: You know, I’m not such a big fan of company events myself. I don’t like all the organizations involved. I don’t like being told when and where to do things. In fact, I don’t even like big crowds of people.
W: But, in today’s society these are the ways we connect. Social networking has boosted my career in so many ways. Well, take last week for example. (21)1 was at a club when I saw an old friend I hadn’t seen for a long time. He started talking about his friend who was looking for a computer programmer.
M: And you got the job?
W: Yeah! (21)The next day his friend called me and yesterday we signed a contract. I’m going to be setting up their company website, and the money is pretty good.
