Sally: Do you think they would be able to do that for me straightaway? Sam: Well, I should think we could have it done today. It would be wise to do that. You could have fractured a bone. Sally: I am a little bit nervous, because we are due to leave later this evening, and you know how long these hospitals tend to take.
