Slipped

He slipped the pen off the desk and into his pocket.

The book slipped from his lap and onto the floor.

She slipped out of her dress and into a swimsuit.

He slipped a piece of paper into the envelope and sealed it shut.

The piece of paper slipped from the bulletin board and fluttered to the ground.

He slipped out of his wet clothes and into a dry towel after a refreshing swim.
