The Luggage is one of the iconic Discworld characters, but did Terry Pratchett ever explain where the inspiration came from for the sociopathic walking trunk with internals that seem to act like the TARDIS (a box that is much much bigger on the inside, from Doctor Who)?
In the Dedication of Sourcery, Terry Pratchett writes:
Many years ago I saw, in Bath, a very large American lady towing a huge tartan suitcase very fast on little rattly wheels which caught in the pavement cracks and generally gave it a life of its own. At that moment the Luggage was born. Many thanks to that lady and everyone else in places like Power Cable, Neb., who don't get nearly enough encouragement.
