input: Please answer the following: W: Nice to meet you here, Tim. I'm buying some Christmas gifts for those who work with me, but it's really a headache. M: Maybe I could give you some advice. Firstly, you'd better divide them into different groups-who were the people that are your friends as well as your workmates and who are the people you do not know well but you see pretty much daily. W: OK, then what should I do? M: For the friends, you want to get them personal gift. Do they like chocolate? W: This is what I always give, but I know Mary is on a diet. M: Does she like fruit or coffee? Anyway, think of the gift that you know your friend likes. W: Well, I think fruit is helpful to keep fit. What about the rest of them? M: Leave cards in their mailboxes or on their desks. W: Christmas cards? M: Yes, you can afford that. More importantly, it's true of them that you're thinking of them. W: Thank you for your suggestion, Tim. You really have saved me and my money as well. What was said before this conversation?
