W: Dad, you always love me, don’t you?
M: Sure. But, wait, wait. What’s on your mind?
W: Well, I saw this great offer for a free cell phone here in the newspaper, and...
M: Free? Nothing’s ever free.
W: Well, the phone is free... after a $5 mail-in rebate.
M: Ah, so that’s the catch. And why do you need a cell phone anyway?
W: Dad, all my friends have one. I can use it to call you in case the car breaks down.
M: Have you considered the fees?
W: The monthly charge for this service is only $29.99, with 1,000 free weekday minutes nationwide, and unlimited weekend minutes. Plus, unlimited, anytime minutes for anyone using the same service.
M: I don’t know.
W: And you can roll over the extra minutes to the next month instead of just losing them. What do you think of that?
M: Yeah, but what is the term of the service agreement?
W: It’s only for a dozen months.
M: But what if you cancel early?
W: Um... Ah, there’s a cancellation fee of $200, but with...
M: Two hundred bucks!
W: Yeah, but you won’t have to worry about me while I’m driving the new car.
M: New car? What new car?
W: The new car you’ll need to buy so I can use the cell phone. I mean, what’s going to look like if I’m using a cell phone in our old car.
M: Teenagers. What’ll they think of next?
