This poem takes place in the timeline where the androids destroyed all the Z-Fighters except for Gohan and Trunks, and Bulma. Trunks thinks of the death of his brave father who he never got to meet.

I Love You, Dad...

I was only one year old, dad
When you went to fight.
I don't think you said good-bye.
But, dad, it's all right.

Because you went to fight
To save mom and me,
To save everyone on earth.
You're a savior, see?

I was only one year old, dad
When you went to fight.
But now I'm fourteen years old,
And I think of you every night.

I always wondered how you were
Before the day you died.
Gohan said it made mom really sad
And every night, she cried.

I wish I got to meet you, dad
To hug and talk with you.
To say, "I love you dad."
And hear "I love you, too."

I want mom to stop crying
Even if she tries to hide the tears
Be there for us, dad, please
To chase away our fears.

But you're gone, dad
And it hurts to think of it so
The pain still remains
From all those years ago.

I hope you're watching down on me
Because everyday, I train.
Gohan teaches me how to fight
Even in the rain.

Dad, I hope you're proud of me
As I train everyday
To beat the bad guys and save the world
Because I know that's the way.

Dad, I hope you're listening
Because I'm saying "I love you."
Mom loves you, too, dad.
And I know you love us, too.

Thanks to Goten's Girl12, I was able to find out the correct age of when Trunks actually trained. He was about fourteen as she said. I had put eight years old...Thanks Goten's Girl12
