Mom: Excuse me, how much is the spin age?
Vendor: 3 Yuan per kilogram.
Mom: That's too expensive. What about the carrots?
Vendor: The same.
Mom: How about 2.5 yuan a kilogram? I come here all the time.
Vendor: Come on. I'm out on a limb here. How much do you want?
Mom: Two kilograms of carrots and one kilogram of spin age.
Vendor: All right, all right. Sold. Goes for 7.5 Yuan.
(Mother gives 10 Yuan to the vendor.)
Vendor: Here is your change.
Mom: Daniel, would you like some beef for supper?
Daniel: Cool! I like beef. And I try to be stronger than Popeye.
Mom: Sure, honey. But you are going to buy it by yourself.
Daniel: Excuse me. How much is the beef?
Vender: Sorry kid, it's pork. We sold out all the beef.
Daniel: That's a shame, thanks anyway.
