Jack: Ann and I are having a few friends to dinner. Would you like to join us?
Sam: Yes, that will be great. Can I bring Jane?
Jack: Of course. The dinner is next Friday. Can you come at around 8pm?
Sam: We will be there.
Jack: Now Jane is a vegetarian, isn't she?
Sam: Yes, but she eats fish as well.
Jack: What do you call people who eat fish but are otherwise vegetarian - pescatarians?
Sam: I'll take you word for it!
Jack: What about you? Is there anything you can't eat.
Sam: I eat pretty much everything except cheese. I am not completely sure why, but I am strongly allergic to cheese.
Jack: OK I've got that.
Sam: Are we going to complicate your dinner too much?
Jack: Oh no, don't worry about it. I am sure that Ann will find something she can feed us all with. She always does.
