The saddest part of traveling is not the last day of your trip. It is not saying goodbye to the lands that take a piece of your heart.
The saddest part of traveling is not when your airplane taxis on the runway of your home airport and you realize that you are home.
The saddest part of traveling doesn't come until a few days after you return home. It is the day you finally zip up your suitcase for the last time and roll it down to the storage shed. It's when you carefully place the suitcase in the corner and let go of the handle for the last time. It's when you start to close the door, and then open it again just to take one last look at the bag that went everywhere with you.
The saddest part of traveling is the day when you put away your suitcase.
Because that is the day when you realize your adventure is officially over.
