I lived at the best hotel, exhibited my clothes in the most conspicuous places, infested the opera...I spend money with a free hand, and meantime watched the stock sales with an interested eye.
首句中Butterfly idleness就是说他自己“清闲得如同蝴蝶一样”。类似这样的修辞手法很多，但是是我们自己创造不出来的，但是却可以通过参考别人的托福口语表达方式来丰富自己的词汇资源。

Nevertheless, occasionally, I enjoy the butterfly idleness. It is an entirely new phase of existence. However, I am not the one who was born with a silver spoon in his mouth so I dare not to spend the money with a free hand...
