Someone had left a string of real pearls to be restrung and the assistant had made a mistake.

有人把一串真的珍珠项链留在店里重新串线，店员给搞错了。

Well, it would be, except that I left string theory, because I decided it was a dead end. Yeah, she went behind my back to help someone else to prove me wrong. My rival, no less.

按理来说是。可是我已经不研究弦理论了，因为我觉得那是条死路。而她背着我帮别人证明我错了。而且那人还是我的宿敌。
