She wasn’t just fiddling with the hem of her shirt or tapping her fingers aimlessly; it looked almost like she was trying to tell her something. ‘Is she signaling me?’ Sandra wondered, her curiosity piqued.

Her thoughts raced as she planned what to say to her, how to appear friendly and not scare her off. ‘Maybe a joke about the food, or a comment about how long the flight is?’ she thought, trying to come up with the perfect icebreaker.
