As a Pillow

I have the History of the English Language class in the second period today.

Prof. Hotta always lectures with an imposing mien, so I appreciate his class.

But there's one thing I'm not satisfied with is his too long introduction of each lecture.

Today he spent 45 minutes for introduction, which means there was only another 45 minutes left to lecture.

He often use the expression "枕として ( 'as a pillow' which is a Japanese expression meaning 'by way of introduction' )" berore the introduction.

Soon after he begins to speak, most of the students drop asleep.

His makura story becomes a real pillow at this moment. ヾ(￣o￣;)
