Hello, Jane. What do you do in your spare time?
Well, nothing special, reading, watching TV, walking, and so on.
Don't you have any hobbies, like stamp collecting or things like that?
No, I don't have any hobbies. How about you?
I like collecting antiques. It's expensive, but it's a lot of fun.
Really? How many collections do you have?
So far I have more than 500 collections.
Among those collections, which is the most expensive?
