M: The weather forecast says it will rain today.
W: Yeah, doesn’t it always? They’ve been saying that for a week and I haven’t seen much sign of it so far.
M: Yeah, but look. This time maybe they’re on target. The sky’s very dark. I got a feeling the rain will be heavy.
W: If it’s raining heavily after class, wait for me and I’ll bring you an umbrella.
M: That’s kind of you to offer, but don’t worry I’ll probably just wait it out.
W: By the way, what are the chances that you might be able to have a word with Professor Simpson in Criminology class? We still need some resources for our Psychology project and his input might help.
M: I could ask him, although I don’t know how eager he’d be to give us information about such a topic.
W: Oh, come on, he’s always so helpful. Why would he even hesitate?
M: Well, he has this mind set, which opposes the notion that criminals must necessarily be psychologically abnormal. He feels it’s just a stereotype.
W: Ok. But when it comes to certain crimes like mass murder, there must be a few "marbles loose".
M: You would think so. But it’s hard to convince Simpson that anyone’s crazy.
W: Perhaps he’d make a good reference source in the section where we include counter-arguments to our main thesis.
M: Good thinking. Let’s give it a shot.
W: That’s the spirit!
