说实话,您的英语不敢恭维,无论是从中国重视的语法教学,还是北美的语言成语习惯。Don't so serious. Can we consider it just a joke? Nothing is more important other than the real feeling of what you feel and where you live. Move on.
形容词直接否定不能直接用don't , 要用don't be , 其次,我们习惯说take it easy, 质疑你不是开玩笑的时候,我们会说are You serious ? 用词不可太重。
Take it easy, It's just kidding, What matters is What We feel and where We are. JUST KEEP GOING.
