I've decided to use two characters from my novel to make this point.
"I wish I could change the past..." he said to himself, exasperatedly, in a whisper.
* * *
Zakk was sleeping. Hyperactive adrenaline junkie that he was, his recovery periods were nothing if not frequent, but he was awakened by the unimposing, rhythmic beeps that indicated that someone was at his door.
"Come in," he said, at which point the computer unlocked the door, which slid open. Standing there was a rather meek-looking Nevan, only a silhouette visible, as the combination of purple and orange characteristic of twilight shone through the window behind him, preventing the rather bleary-eyed Zakk from seeing clearly. Even so, they had been friends long enough for Zakk to identify him before.
"Zakk, I'd like to talk to you," Nevan said.
"Yeah?" Zakk said, filling his lungs with oxygen as he sat up in his bed and swiveled his body to the side, his normally spiked hair hanging freely over his face. "What's up?"
"Well, I wanted to talk to you about something."
"About what," Zakk said, furrowing his brow slightly.
"Well," Nevan said, pausing for a moment. "You know, we haven't always gotten along..."
"Tch. No kidding," Zakk said with a slightly laugh.
Nevan looked to the side. "...Yeah. Well, I wanted to try something."
"Okay..." Zakk said, betraying with his voice not a small bit of skepticism.
"I want to change the past," Nevan said.
At this point, the look on Zakk's face had progressed from skepticism to slightly amused contempt. "You're going to have to give me more."
"Just try this," Nevan said. "Close your eyes."
Zakk stared at Nevan for a moment. Neven nudged him from a distance by simply moving his neck and opening his mouth slightly, as if saying, "Yeah, come on..."
Zakk complied, and they both closed their eyes.
"Now," Nevan said, "think back to when we got into that fight when we were 12. You remember that?"
"Of course I remember that, man."
"Do you...remember what you said to me?"
Zakk was perturbed. "Do we have to do this?"
"Just stay with me," Nevan urged.
"I said that you were worthless; that the reason you were always alone was because you have..."
Zakk stopped, very uncomfortable, and visible and audibly shaken.
"Keep going," Nevan said, his voice shaking slightly.
"I said you don't have anything to offer anyone... And I didn't just say it. I screamed it in your face. And then I shoved you."
Nevan took a deep breath. "If you could do it over, would you?"
"Nevan," Zakk said, exasperated. "How could you even ask me that?"
"Would you?"
"Of course I would!"
"Then let's do it. Right now."
"Do you have some technology that I don't know about?"
"Use your mind. We're in that room -- right now. You're angry. All of my annoying habits have gotten on your nerves. You're ready to explode. Think about what was in the room. Feel what you were feeling. I'm there with you. Wer'e in each other's faces. But this time, what do you do?"
"Nevan, I..."
"We're both in our bodies back then...in our minds. We're sharing the same experience. We can do it over. What do you feel?"
"I'm furious. You never stop. Everything is always negative. You shoot down everything positive."
"Nevan," Zakk began again, his eyes still closed, assuming his twelve-year-old self. "You know...sometimes you make me angry."
"Oh, really?" the faux twelve-year-old Nevan replied. In a characteristically depressed-sounding voice, he continued. "I...just... I can't help it."
Zakk felt a familiar flash of anger. "That's what I'm talking about. Do you have to be like that?
Nevan was inhabited by familiar feeling of guilt and sadness. "I'm sorry!"
"I...know, man. But you know what -- you are who you are, and I like you. We're friends. I just need to work on my anger. I'm sorry for being so impatient."
In their minds, they shared an image of Nevan and Zakk sharing a glance.
"Thanks.I'm glad we're friends," Nevan said. "You know you're on of my only friends."
Zakk laughed, with a genuine smile as well. "I'm glad we're friends, too."
They both opened their eyes.
"Hey Zakk," Nevan said, hearkening back to their alternate past. "Remember when we were twelve and we had that great conversation? I'll never forget that."
"Neither will I."
"I mean, I know I could....can be a bit much, and I know you didn't have to treat me so well."
Zakk sighed. "Nevan...Are we just pretending?"
"Zakk, as far as I'm concerned, we just rewrote our history."
"I find that...cool and...and disturbing."
"Disturbing... Why?"
Zakk walked toward his window, looking out at Eidian City at dusk.
"I mean, what if someone does something really horrible -- I mean, really, really horrible, and then just decides it didn't happen."
"I did think about that."
"And?"
"Well, we both know what happened in the real world. I'm not pretending it didn't. You feel bad about what you did, and I'm giving you a second chance to make things right. We're not papering over what happened. I'm just forgiving you. You said if you could do it over, you would. Well, some people say you can't take back what you did. But as long as we're both still alive, I think we can. And we did."
"So, it's not that I never made the wrong decision. It's that I got it right the second time..."
Nevan smiled. "Now you're getting it."
