"I don't know if I paid attention to it or not. If I appreciated what I had." Soldat considers a moment, going over the scattered memories they have from before the war. "I think. Maybe the person I used to be. He did appreciate it. He's the one who went to war, and he had. There was training beforehand, there was time between the draft letter and shipping out, to know what was being lost. And he seemed the type to really live life."

They shake their head. That may not really be what Tidus means by "pay attention to", but they definitely couldn't say what the person they used to be paid attention to. So they finish: "And I definitely appreciate it now."
