A：May I help you, sir?
B：Yes, please. I'd like to buy a gift for my younger brother. He's going to take a trip to South America.
A：By air or by sea?
B：By air. So my gift should be quite light. What can you suggest?
A：How about this wallet? It's made of fine leather.
B：My sister already gave him one. I like something unusual.
A：This gift is the best for a man who has everything.
B：Oh, a nice handkerchief. That's a great idea. I'll take it.
