Before the exam, the teacher reminded us of the important points again just to make sure.

He's just wasting time and accomplishing nothing.

He ended up receiving hate on the internet.

After failing, he blamed himself and was biting his own navel (figuratively expressing deep regret).

I doubted what I heard when he spoke.

He plans to quit the company as of next month.

Despite being sick, he continued to work hard.

He can play various instruments, starting with the piano.

The hospital was closed despite the opposition of the residents.

I ended up saying something that spoiled the start of his new project.
