I'm reading a book called "Mini Shopaholic".<br/>Here are the dialogues..<br/><br/>‘So … you’ll never tell him?’ I venture. ‘Ever? He’ll never know it was you?’<br/><br/>“ He will never know. ” She looks at Suze dispassionately. “ Please stand aside so I can leave. ”<br/><br/>That’s it? No high fives, group hugs, let’s-do-this-again?<br/><br/>I wonder why "let’s-do-this-again" uses hyphen to link the words?<br/>Could anyone tell me the meaning of it?
