The Blacks and the Whites are good neighbors. They know each other well. Sometimes they have dinner together.
One day, Mrs. Black invites the Whites to have dinner again because it is her birthday. In the afternoon, she comes home from work early. On the way home, she goes to the market first. She buys some beef because Mr. Black likes it best. And she knows that Mr. White likes chicken and Mrs. White’s favorite food is fish. So She buys chicken and fish. She also buys some vegetables and fruit. She wants to get everything ready for the dinner.
When Mr. Black comes back home, Mrs. Black is busy cooking. “Happy birthday!” Mr. Black says and brings her a bunch of flowers. “Oh, thanks. What beautiful flowers! Would you please put them in the sitting room? I’m busy now.”
“OK,” says Mr. Black. “And I can help you put the candles on the birthday cake.”
“A birthday cake?” Mrs. Black says, “ I forget to buy it.”
“Never mind. I’ll buy it now. I’ll be back in a few minutes.” Mr. Black says while he is running towards the door.
Just then, the doorbell rings. They are the Whites. In their hands there is a big birthday cake.
