Sean felt free, the thoughts and relationships with other people which had weighed him down over the past months slipped away.

For all the effort to keep control of the message, a few unintended thoughts slipped through.

It had been a mistake to let his thoughts slip to her.

Slowly, his thoughts slipped out of contact with his situation.

The thought slipped to the back of his mind as she ushered him into the commissioner's office.

The thought had slipped into her mind and down through her fingers.

That particular thought, therefore, slipped easily out of his consciousness and into words.

As she moved along the pathway, her thoughts slipped rapidly, one to the next.

The other thought slipped free before she could catch it.

Already the thought of Ben's house had slipped from his conscious awareness.
