I wanted a piece of the place I'd once called home.

"And the King has not called for you once since my attack."

He usually called once a month with the same speech.

He called once in a while, but that was it.

A young man once called at the office of a certain newspaper, and asked for a job.

He once called me from my desk to meet his friend.

Throughout their long conversation she hadn't once called him anything.

He also once called my mother when she was very ill.
