As I look at my bags I think of the personality they have acquired over time. You can say they are battered, but that won't be true. They are travel worn. Aged with being handled over many cities, people, trains, planes, dropped, pulled. Still strong & sturdy, they bear their travel marks proudly, as their identity. The stickers which refuse to leave them make them unusual.
Like a boxer who has won many fights, and hopes to win many more, who bears his scars with pride.
And though Rincewind's might be smart, my luggage has their own personality.
