I was thinking and decided it wouldn't be right if I didn't add a Gohan POV.
--------------
We see Gohan walking alone on a grassy hill. He is now 15 years old. Three years since the day. As usual, he has his hands shoved in his pockets and has a wistful look on his face. Suddenly, he stops and looks up at the night sky. Billions of tiny lights of the past shine down on him. He sits down, and after a while he just collapses and lies down on the grass below him. He sees a constellation that looks like the shape of his dad's head and silently cries. Wiping away the tears as if making himself presentable, he speaks.
"Dad, I want to have a man to man talk. Before you say anything, yes, I think I am a man because I was never a boy. Piccolo made sure of that!"
He paused, remembering the old times. Remembering how Piccolo made him survive in the wilderness when the Saiyan's came.
"You know, so many people were so aggravated when you died, most of all me. And Mom. Mom was in pretty bad shape, especially when she was pregnant." He puts his hand on the edge of his mouth as if whispering a secret.
"Let me tell you that you were lucky to be up there when she was going through labor. My ears haven't fully recovered yet." He rubs his ears and puts his hand back to his side.
"I guess what I'm trying to say is that it's so hard to understand why you had to go. So many people loved you. Everybody loved you with the exception of the 'bad guys'. And it's real hard with Goten here. I guess Dende felt sorry for us and decided to try and give a piece of you back. So many times I look at him and think that it's you. *Sigh* We've all cheated death so many times. I guess you decided that you should repay Dende for us. That way we could all live on and keep on cheating! Right?" A soft breeze blows past and ruffles his hair. Gohan smiles.
"I understand, Dad. It's just so hard to believe everyone's favorite person is gone. Even Vegeta was tormented for weeks. I guess he didn't want to be on the top after all. *Chuckle*" Suddenly, he frowns.
"Dad, I'm so sorry. I should have finished him off when you told me to." His voice was cracking now. "I feel like your death was my fault. I was the one who should have defeated him the first time. If I hadn't let my arrogance get in the way, you would still be here. You would be here to watch the little mini-you grow up more and more like you everyday. You would be here to see my work and be proud of me. Mom wouldn't be so depressed all the time, and Goten would have had a father. I try so hard to be the father you would have been, but all I am is a big brother. I'm sorry Dad, I failed." A rough gust of wind sweep around him. He could almost hear his father's lecturing voice. His mother called him in for dinner.
"We'll Dad. I have to go now. I guess all I wanted to say was that I miss you very much. I love you Dad. Bye!" Gohan ran to the house using his Saiyan speed.
As Gohan was drifting off into sleep, he could almost hear his father's voice.

Up in heaven, Goku looked down at his son and softly whispered something. "You never failed me son. I'm very proud of you. I love you."
