Just one word but it narrows things quite a bit. He is male. So we’re starting with a male. He is nowhere near the same as I. If I, being a male, refer to myself as he in order to fill in some background it is still much less personal. He is over there. We are looking at him, not being him. But that’s the first choice and any choice leaves most of what could be behind.
He walked alone.
Well that’s kind of sad. Or maybe he just left his girl friend’s house and He’s about to share how this is the best day of his life? Not this time. He’s walking alone because, well let’s just see…
He walked alone through the deserted streets.
So he’s not just walking alone there is no one else around. He could have been alone in a crowd, everyone else with someone to kid around with, someone to hold hands with or at least someone to tell off or be told off by.
He walked alone through the deserted streets kicking bits of fallen building out of the path.
Seems like something bad must have happened, buildings falling down, I bet he needs to find a path around a car in a minute…
He carefully made his way around an old rusty Ford, the original color might have been blue or brown or black it was hard to tell.
Whatever happened must have happened a long time ago and on Earth, where else do they have Fords?
Ford had sponsored the settlement on Earth Three and most of the cars were Fords.
Just messing with you, he’s on Earth, the same Earth as you and me. No space travels in this one.
He looked inside the shell of a car to see if anything of interest had been left behind by other scavengers, nothing, it was stripped clean, like everything else in this town. He knew it was time to leave but this was his home, he had grown up here and even though there was nothing left it was hard to leave. He kept walking. Some of the brick or block buildings still stood, none had glass in the windows, none had intact doorways. He stopped at the entry of what once had been a bank on the ground floor with six stories of offices. He looked in seeing what had been left behind. There were thousands of paper bills littering the marble floor. He could pick them up and become a millionaire, at least according to the numbers on the bills, but the paper was worthless, well it had a use but he had no use for it right now. He chose not to enter the bank but continued walking down the street, being watched by no one and seeing no one. The thought occurred to him that he might be the last person in the whole city. The thought reminded him of his hunger. There was a reason the few that had survived were gone.
