I believe it definitely has to do something with the cotentment. If the journey takes longer than usual, some start narrating a story to themselves, “I’ve atleast reached here starting from nowhere.”
Surprisingly, we don’t narrate a similar story when we’re on actual journey, for instance a train journey between City A and City B if the train gets delayed, we don’t tell ourselves, “Let me get down in between only. Atleast I’ve reached here.” We wait patiently toreach our destination.
So, it basically could be an excuse for laziness when the journey requires us to put in even more efforts.
