Peels of carefree laughter had given away the secluded lunch spot of my new friends.

I heard voices in the mist, carefree laughter, joyful sounds.

The tinkle of china and crystal, excited voices, carefree laughter.

He resented their carefree laughter.

Roxy followed this sally with another discharge of carefree laughter.

Or anything but carefree laughter.

He watched them eat and, listening to their carefree laughter, was content.

Then he broke out into laughter, the carefree laughter of a boy who got away with some well-planned mischief.

He took another deep breath as three quicksilver shadows flickered across the dirty window, the high, carefree laughter of children up to some devilment trailing after them.
