ANDREW: Your older brother is a little strange, I think. DAN: Steve? You think he's strange? Why? ANDREW: He wanted me to come over and watch "Star Trek" with him. DAN: Oh, that. He's a Trekkie. You shouldn't be surprised. ANDREW: He's a what? DAN: A Trekkie. He's a serious "Star Trek" fan. 、So he has all the episodes on tape. And he has a "Star Trek" website on the internet. ANDREW: He even has a website? For "Star Trek"? DAN: Yes, he's a serious fan. ANDREW: I don't understand it, though. He's 27 years old. Isn't it kind of immature to be serious about a science fiction show? DAN: Don't you have Trekkies in Taiwan? ANDREW: I don't think so. Maybe some kids. But your brother is an adult. And he works for an accounting firm. Why should he like "Star Trek" so much? DAN: It's just a kind of hobby. Some American adults are like that. They have some show they like, and they know every episode. Some of them even start to collect memorabilia. ANDREW: Memorabilia? What's that? DAN: They collect all the posters, or dolls, or stickers, or anything that comes out from the show. ANDREW: And your brother is like that too? DAN: Oh, sure. Go in his basement some time. You will see the walls are all covered with "Star Trek" stuff. ANDREW: That's too strange! Doesn't he have trouble finding a girlfriend? DAN: Maybe a little. It's true some Americans agree with you. They think it's too immature. ANDREW: I like "Star Trek" sometimes too. I liked the movie. But I don't think of it seriously. It's just for fun. DAN: He does it for fun too. Don't worry. He's not a maniac. He just does it for fun.
