一声“大声叹息”意味着她认为那一刻的你是一个白痴，而且不明白自己为什么浪费了这么多时间站在这里来跟你争论“无关紧要的事”。

A "loud sigh" means she thinks you are an idiot at that moment, and wonders why she is wasting her time standing here arguing with you over "Nothing".

如果我是你，不会将时间浪费在这里。

I would not waste my time pursing that.

在这里我想提醒大家的是：并不是越出名的律师就越适合你，小案子请大律师本身就是一种浪费。

Here I would like to remind you: not the more famous lawyers for you, a small case, please counsel is a waste of itself.
