This dialog should be between 20 and 24 lines (for two people). In this dialog people should greet appropriately, ask one or two questions from the greeting vocabulary, and then ask and answer at least 5 questions from the numbers and time vocab. They then need to say goodbyes. You may use ONE line that you get from a translation site, but you must know precisely what it says.
