while I listened to Nature podcast, I came across some new words to me. Here they are.

sticky situation:

sticky:

adjective: moist as with undried perspiration and with clothing sticking to the body (Example: "Felt sticky and chilly at the same time")
adjective: hot or warm and humid (Example: "Sticky weather")
adjective: hard to deal with; especially causing pain or embarrassment (Example: "A sticky question")
adjective: having the properties of glue


生活中总是有很多让人“左右为难”的事情，比如说今天又有哥们向我来借钱！这个哥们声称他有一笔赚大钱的买卖，但苦于资金有限，所以想先在我这里支点银子，等赚了钱之后，不但立刻归还，还会另有酬劳；说实话，我一点也不看好他的买卖，但是，不借吧，伤了哥们的和气；借吧，又恐这钱是有去无回；我就象Michael 咨询了一下该如何处理。

　　 Michael说这真是一件sticky business，因为在美国大笔借款一般是到银行去贷款，所以他劝我应该直截了当地回绝那个哥们。接着他说自己现在也遇到了a sticky business，他的父母希望他能尽快回国，而他却想留在中国，正在左右为难；我感叹了一句You're in a situation that is difficult to deal with. 他说这就是 sticky business的意思。我想了一下：stick是“粘”的意思，sticky当然也就有“粘性的”的意思，“粘的（sticky）东西粘到了手上可真是不好办”，所以sticky business表示“让人左右为难的事情”也还是可以推理出来的，只是我以前总是用difficult、hard这些词，看来还不如sticky business形容起来更加形象。不过Michael告诉我，sticky business在口语中用的比较多，正式场合或者是书面语中，还是difficult等词出现得频繁
