Life as an electron

The universe is a lonely and static place, to the average electron. Were we to grant it some sort of awareness and conciousness, for the sake of the story, some sort of senses with which it is aware in some semblance, think on how different the life of individual electrons might be...

Your average interstellar hydrogen's electron is very lonely, perhaps remembering a time when things were different before the big bang. An electron lucky enough to be a copper's electron would have sat bored for millions of years till someone dug it up and put it in a computer, where it started migration, perhaps even to different types of atoms altogether.
