Tom's mood goes down and he turns to another entry.

It was partly his fault that her mood had gone from bad to worse over the past two weeks.

She caught sight of me and smiled, her dark mood gone.

Just whisper about taxes around a stock market and the mood goes sour.

Even before the radio had broken in, the mood had gone bad.

In that crazy time, my mood went up and down like an elevator.

My own dark mood fortunately having gone unnoticed as yet so far.

But the mood had gone out of him today.

His good mood went as fast as it had come.

These moods may go back and forth over a period of hours or days.
