Inviting for cup of coffee
A: John! Wait a second! I was just heading downstairs for a cup of coffee. You want to come? I’ve got some good news!

B: Sure. Let me just grab my wallet. You certainly do look happy this morning.

A: I am. Don’t worry about getting your wallet. It’s my treat.

B: This is a first! You must have won the lottery.
 

请喝杯咖啡
A：约翰，等一下。我正要下楼喝杯咖啡。你想一起来吗？我有好消息。
B：好啊。等我拿钱包。今天早上你看上去真高兴。
A：我是高兴。别去拿钱包了。我请客。
B：这可是头一回。你一定是中彩票了吧。
