I can ’ t attend the meeting in Washington . I ’ Ve proposed you as the most able substitute .   But I ’ Ve never been on a business trip before !   It ’ s easy enough . Just make sure you keep track of all your expenses . The accounting department will reimburse you for all your meals and travel expenses .   So the company will pay for everything ?   Yes , but when you send in your expense report , you also have to file a report summarizing your trip . It ’ s not just a big vacation , you know .   That sounds good . But what do you want me to do there ?
