By the time Lucía landed in Chicago, she had been awake for almost twenty hours.
She had flown from Madrid, changed planes in New York, and eaten two terrible airline meals.
All she wanted was a hot shower and a soft bed at her sister's apartment.
She waited at the baggage carousel until almost everyone had left, and finally a blue suitcase like hers came around.
It was only when she opened it at her sister's place that she realized her mistake.
Instead of her clothes, she found three cameras, a pile of maps, and a notebook full of drawings of birds.
Someone had taken her suitcase, and she had taken theirs.
The next morning, she called the airline, and a woman told her that another passenger had reported the same problem the night before.
His name was Daniel, and he was a wildlife photographer who had come to Chicago to take pictures of birds along Lake Michigan.
That afternoon, they met at a coffee shop and swapped suitcases.
Daniel laughed and said that he hadn't slept at all because he had been so worried about his cameras.
Before they said goodbye, he gave her one of the bird drawings as a thank-you.
