Isolation can be a theme too. The time traveler may feel isolated from their own time or the people in the time they visit because of their unique situation. Their love might be the only connection that bridges these gaps, like in some stories where the time traveler is an outcast in the time they end up in, but their love gives them a sense of belonging.
One great 'time travellers love story' book is 'The Time Traveler's Wife' by Audrey Niffenegger. It tells the story of a man with a genetic disorder that causes him to time - travel involuntarily and his complex relationship with his wife.
Maybe the dog has some special senses that can detect the unusual presence of time travellers. It could bark loudly to scare them away or stand guard protectively.
One interesting time travellers story is 'The Time Machine' by H.G. Wells. It tells of a man who builds a machine and travels to the far future where he discovers two different races, the Eloi and the Morlocks. Another is 'A Connecticut Yankee in King Arthur's Court' by Mark Twain. Here, a man is transported back to the time of King Arthur. And 'Doctor Who' is also full of time travel stories, with the Doctor traveling through time and space, having adventures and saving different civilizations.
The Doctor from 'Doctor Who' is extremely famous. He's a Time Lord who travels through time and space in his TARDIS, which looks like a blue police box on the outside but is huge inside. Another is Marty McFly from 'Back to the Future'. He's a regular teenager who gets thrown into time - traveling adventures. And then there's the Terminator in 'The Terminator' series. It's a cyborg sent back in time with a specific mission.
Not necessarily. 'Fellow Travellers' could be inspired by real-life situations but might have been fictionalized to make it more engaging or to fit a certain narrative.
Well, in this story, the dog's role is likely very crucial. It could be the first line of defense. Since time travellers are an unknown and potentially dangerous entity, the dog's presence and its ability to react quickly can be the difference between safety and danger. It might not understand exactly what time travellers are, but it knows that something unusual is there and that it needs to protect its owner. For instance, it may jump in front of the time travellers to prevent them from reaching its owner, using its body as a physical barrier.
In fact, 'Fellow Travellers' is a work of imagination. The plot and characters were crafted by the author's creativity rather than being drawn from real-life situations.
Two travellers were walking through the forest when they suddenly saw a bear. One of the travellers quickly climbed a tree. The other, not being able to climb, lay down on the ground and pretended to be dead. The bear came up to him, sniffed him, but thinking he was dead, left him alone. After the bear had gone, the traveller in the tree came down and asked his friend what the bear had whispered in his ear. His friend replied, 'The bear told me never to trust a friend who deserts you at the first sign of danger.'
