Funny Holiday

Ben: Hello, David. Tomorrow I am going to sunny Australia! It's so warm there. I can swim all day.

David: But it's winter time.

Ben: When it's winter in China, it's summer in Australia. Where are you going on holiday?

David: I am going to Russia. It's winter there. I can skate (滑冰).

Ben: Do you have warm clothes?

David: Of course! I have winter coat and some new nice skates, too.

Ben: I have a bathing suit (泳衣) and sunglasses. How do I look?

David: Cool! Time to go. See you!

Ben: See you!

(After they get to the place, they find something wrong.)

Ben: Oh, my God! Where are my bathing suit and sunglasses?

David: Oh, no. This is not my suitcase (旅行箱). How can I skate with a bathing suit?
