I write, but only sometimes

I write, maybe only for today

          Kevin and Dennis floated silently in the seemingly endless void. They haven't talked at all in centuries, maybe even millenia. And even that's just a guess. It turns out, it can be difficult to tell time without a star for your ball of rock to rotate around. Most of the stars have collapsed in on themselves by now.

          "Hey buddy, still alive there?" Dennis asked. He couldn't actually say any words. There isn't a proper medium by which noise can travel through in empty space.

          "You asked that not too long ago and it is still now funny." Kevin responded. It took a while for the two to get a hang of talking telepathically but it isn't like they had much else to do. The hard part was stopping other people from peeking inside your head, as opposed to actually getting your thoughts into theirs.

          "What'cha thinking about?" Dennis asked. Multiple human lifetimes of no talking could contribute a lot to boredom.

          "I don't think that I have had any thoughts since the last time we've had this conversation. I've been focusing on this blissfully eventless sile-" he was interrupted.

          "I've been thinking about food lately. I haven't had pizza in a while. Pepperoni and jalapeno was the best. What was your favorite?"

          "It was ham and chee-" he was interrupted yet again.

          "I know what it is. We've had this exact same conversation over a thousand times."

          "Then why bother asking?" Kevin asked back.

          Dennis didn't respond. He just closed his eyes and went back to their endless floaty, meditative silence. It was going to be a few more months or years before they talk again.
