20.all thumbs笨拙的，笨手笨脚的

A: Hey, Bea. Can you help me out? I don't seem to be able to button up the back of my dress. 

嘿，碧儿。你能帮我一下嘛。我系不上裙子背面的扣子。

B: Sure. Let's see if I can do it for you. 

当然可以。我来帮你。

A: I guess I'm all thumbs because I'm so nervous. I'm already late for my date. 

我觉得我是因为紧张而笨手笨脚的。我约会都要迟到了。

B: Well, I suppose that being so nervous would make you clumsy and awkward. But don't worry. I'm sure your date will wait. 

是啊，我也觉得紧张会让人笨拙尴尬。但是你别担心。你的约会对象肯定会等你的。
