M: Did you watch television last night?
W: No, I didn’t. I seldom watch it anymore.
M: Why is that?
W: There are only a few programs that I find interesting enough to watch.
M: Well, there are some shows that I never miss. Don’t you ever watch star trek?
W: Yes, I watch it now and then but it isn’t something I can’t live without.
M: I’ m a big fan of star trek. I love the characters and the idea of traveling through the universe at speeds faster than light is fascinating to me. I really like all the different life forms that they create, too.
W: I know all about fans like you. I think they call you "trekkies". Is that right?
M: Yeah, that’s what they call us.
W: I know there are some good shows on TV, but there is so much violence on so many of the shows. A person could witness more killings in one night that a soldier would encounter in months of warfare!
M: I agree with you there. However, there are some shows that I never miss.
