Their words were only accidents in the mutual silence.

After a full minute of mutual silence, she said, "I really shouldn't be here."

For a long moment they sat in mutual stunned silence.

In mutual silence, he led her down the hill.

There was a mutual silence as they allowed me to digest that idea.

After another mutual silence, he let go of my hands.

They set out in mutual silence, walking quickly to keep warm.

Our mutual silence encourages her to keep talking and she continues haltingly.

When she finished, there was a long period of mutual silence and musing.
