On the chilling morning, my parents and I came to Detroit Wayne Airport. Detroit, the place where they first stepped on the land of America, was also their last stop.

During the past years, I hadn't had the chance to talk to them too much because of my wanderlust. Now the valuable three months' reunion had come to the end. And I don't know when to see them next time.

After they disappeared from my eyes, I looked around the airport. Sun came in, the red waiting line stood there long and lonely.
