The plane was only in the air for a couple of minutes __________ the wife, Marcie, fell asleep, leaving her husband Daniel and my sister sitting next to each other in silence. Maybe it was a feeling of __________ that sparked（引发，触发）it, or maybe it was the need to __________. Whatever the case, within minutes Daniel began to tell their own story.
