I read aloud.

“Hello, old man! If you’re reading this letter, then you made it: you’re 100 years old! Congratulations to you.

“Or, congratulations to me, I should say. I set you up for your success, right? Come on, give me credit. I’m the one who signed the contracts, took the money, made the payments.

“Yes, there are some downsides. You should be 100 years old but you’re probably not living on Earth. Part of the agreement, right? I have no idea which planet you ended up settling, either. That’s one reason why you’re getting a preserved paper letter. If you’re reading this, you remember all of this. It’ll be as real to you as it is to me. And you know all the details. Hell, biologically, you’re younger than me now, because they gave you a new body, assuming they lived up to their end of the agreement. You should now be 25 biologically, which, yes, you know. Yes, you’ll be another color; you won’t be white. Small price, right? They weren’t sure whether you would be blue or green. Said both of those were possible with our genes. Wish you could write me back and tell me.

“Hard to write this. I know things but you know them, too. But I write to think, to make sense of it all. I never expected the things to happen which did. The war. Getting frozen. Sent to storage in space, then returned to Earth. I mean, as you know, I know these things, but it’s all abstract to me. Happened to me but I wasn’t conscious of it. Not this version of — well, yeah, you know.”

I stopped reading then. I knew what the letter said. I just wrote it yesterday. Realizations were creeping up. I’m a slow thinker but I usually get there.

So I took in the shimmering individual standing before me. Gorgeous guy. Blue. Azure. Well built. So tall, his thick, glossy black hair brushed the room’s ceiling.

“You’re me,” I said. “But you don’t look anything like me.”

He snorted. “Yes, I know. I’ve seen myself and I see you now, along with the old photos of you. They gave me options to change my appearance and I took them.”

“I see.” I smiled.

“I mean, wouldn’t you?”

“I probably would. Well, I did, because you’re me and…anyway. So, you made it. I made it. We made it.”

“Oh, yes. It’s quite a future, so improved over this. And you wanted to know what color we’d be, so….” He shrugged.

“You came back to show me.”

He grinned. “Bingo. Well, mostly. I also came back to thank you.”

Stepping forward, he offered me his huge hand. “I don’t want to get mushy, but thank you. Thank you for having the fortitude to persevere. Thank you for the decisions you made and supporting the science. Thank you for trusting it.”

Setting the letter I’d written to my hundred-yead-old self onto the desk, I stood and shook his hand. “You’re welcome.”
