Headphones in, computer on, typing away at my keyboard. The planes jerks a little and the little girl next to me, who can’t be more than 6 months old, starts to cry in her Dad’s face. He tries to calm her down, kissing her head and wiping her tears away. She looks over at me, and I smile.

The dad looks at me with a sigh. “Is she bothering you?” He asks, “I’m sorry, she’s been acting up all day.”
