"Yeah Micky?" Mike looked up from paper he was reading.
"Do you ever think that we're not alone?" he asked, gazing dreamily at the ceiling as he leant back on his chair.
Mike sat up, and peered at him from over the back of the couch. He glanced upwards and considered the question a moment. "No."
Micky turned his head towards Mike. He was reading the paper again. "The universe is so..." Micky paused to think of an impressive word. "Big. And we're just one tiny dot in the midst of it all. Imagine, there could be another world out there, dying to know if we even exist."
"You watch too many movies Micky," Mike said, turning the page of the newspaper.
Ignoring him, Micky continued. "What if there're aliens out there making clones of us and depositing them here on earth, just biding their time until they out number us? What then?"
Mike sat up again and looked at Micky. "Why are you even thinking about it? If there are Martians clonin' people to take over the earth, then we're doomed. How can we, humble earthlings, defeat a race of mechanical clones programmed to destroy? Not even the most powerful human weapon can defeat the perfect craftsmanship of an extra-terrestrial being. Yep Mick, we're all doomed to die. That is," Mike added as he lay back down, "if we really ain't alone."
Micky stared at Mike for a minute, his brain processing the information. His expression thoughtful, Micky leant back in his chair and gazed across the room.
The pad was relatively silent for the next half-hour. Mike continued reading the paper and Micky got up to get a drink of water, only to resume the same position on the chair he'd been siting on.
"Hey, Mike?"
"Yeah Micky?"
"Do you ever think that there are other dimensions, that are spun off from small incidents in our lives, which could've happened but didn't for some reason or other?"
