Idiom:cool one's heels
Meaning:to wait (for someone); to wait for something to happen.
久等；奈不住性子
注：但值得注意的是，英语cool one's heels作为“久等”或“足足等了”的地道表示法，只能用于“白白等了”的情景之中，若“久等”而“白等”时就应该用be kept waiting来表示。比如：对不起，让您久等了。I'm sorry to have kept you waiting.
Example:
1. Newspaper reporters must learn to accept cooling their heels as part of their job.
报社记者必须学会久等，这也是他们的一个任务。
2. Asking him to wait? He had no patience in cooling his heels.
让他久等?他是耐不住这个性子的。
