Tim:  Hi, Susan. I've been wondering when I'd run into you. What are busy with?
Susan: Nice to meet you here, Tim. I'm buying some Christmas gifts for those      work with me, but it's really        headache?
Tim:  Maybe I could give you some advice. Firstly, you should consider        (divide) them into different groups. Who are the people that are your friends as well as your workmates and who are the people you do not know well       see pretty much daily.
Susan: OK, then       should I do?
Tim:  For the friends, you want to buy        personal gifts. Chocolate, for example.
Susan: This is what I always give, but I know one of my friends, Mary, is       a diet.
Tim:  Does she like fruit or coffee? Anyway, think the gift that you know your friend likes.
Susan: Well, I think fruit is helpful to keep     (health). What about others?
Tim:  You can send them cards.
Susan: Christmas cards?
Tim:  Yes, you can afford them. More     (important), it reminds them that you're thinking of them.
Susan: Thank you for your suggestion, Tim. You     (help) me out.
