back in time adventure
You glance over at your friend. You know that you too must leave very soon. She returns your gaze and smiles at you, then begins to unfold a small textile bundle beside her; as she opens it you see she has a beautiful pink Spondylus shell nestled in the folds of the faded cloth. You open your hand and show her the spindle whorl you have been holding all this time. "Oh, it is pretty, let's trade," she says. "Yes, let's," you reply, and drop the whorl on to her hand as she puts the shell into your other hand.
