Brooded

Bob brooded on the matter.

He brooded over his misfortunes.

He brooded over the mistake he made.

She brooded over the bullying done to her.

The storm-clouds brooded over the valley.

And along the entire 40-foot wall of the reception room, a photo-mural of a ragged, depression-era breadline brooded over the sleek heads of the beautifully dressed and elaborately fed tourists.

For a time absolute silence brooded upon the sylvan scene, save for the humming of insects and the twittering of birds.

The red hen has brooded.
