窈窕淑女，君子好逑。你很不愿相信淑女会发脾气吧？谦谦君子，温润如玉。你也很不愿意相信a relaxed and cool kind of person会发脾气吧吧。但是，如果你说你自己 never lose your rag，我可一定不相信。
to lose your rag，丢了一块布？字面意思很好理解，just lose a bit of cloth, a rag? 事实上，to lose your rag 这个短语不只是字面意思那么简单，它其实是说发脾气，生气。to lose your rag means to lose your temper, to become infuriated, to become angry!
举个例子吧。夫妻哪有不生气吵架的，下面的这对小夫妻就lose their rag了。
a: oh i've just about had enough of living in london, i can't bear it!
b: ok, don't lose your rag!
a: do you mind? i'm not losing my rag, you are!
b: i'm not losing my rag, i'm just well angry.
a: there, i told you!
对话中的小夫妻其实都已经 lose their rag 了。妻子说她厌倦了伦敦的生活，在和丈夫谈论的过程中，两个人的说话方式都激怒了对方，以致于最后都 lose their rag
我们再举个例子，例子中的小伙子已经不是动怒那么简单了，他开始动手打人了！
a: do you see that? phil's groping my girlfriend!
b: ok mate, don't lose your rag...
a: too late, i punched him in the face.
生活中，脾气再好的君子淑女也难免发脾气。偶尔发泄一下，lose your rag from time to time，能舒缓你的情绪。不过，记得选对发泄的对象哦。
