The dead are like people trapped inside a nutshell. To those who remember them, the time and space of the dead has frozen in place. The world may change, but the departed remain forever the same.
There are worlds that stretch on endlessly, and worlds that loop again and again like a Mobius strip. The little dog's fate is trapped in one such loop.
To the dog, the future is just as impossible to change as the past.
