'Perfume, eh?' he asked sarcastically. 'You should have declared that. Perfume is not exempt from import duty.'
'But it isn't perfume,' I said. 'It's hair gel.' Then I added with a smile, 'It's a strange mixture I make myself.'
As I expected, he did not believe me.
'Try it!' I said encouragingly.

听了原文很多遍，觉得nostrils的音标应该不是按照这个发的/ˈnɒstrɪlz/，应该是 /'nɒstrəlz/
