M: Amy, did you type the purchase order?
F: Yes. Is there something wrong with it?
M: Have a look. All is correct except the customer’s name. It should be "Snelling", not "Smelling".
F: Oh, yes. I’m ever so sorry.

F: Hi, Jake, how’re you feeling?
M: Oh, terrible, Vanessa. I think I’m going to die.
F: Oh, come on, don’t exaggerate—you’ve only got a cold!
M: It isn’t just a cold, it’s definitely the flu: it might even be pneumonia!
F: Yeah, right. If you just sit around and feel sorry for yourself, you’ll never feel better. What about going for a walk? If you get some exercise and fresh air, you’ll feel fine.
M: Oh no, I’m too sick. I think I need some antibiotics.
