That word I want to use

There has been so many times that I've wanted to use that word
To say it and have a personal meaning like b4
For all the times we've headbutted each other
For all the times you've made me laugh
For every time you said I kicked you out of the bed
I just want to use that word like everybody else
I want you to be here to claim your title
To wear your crown
Many can try but never replace you
They say I'd make you proud and it makes me cry every time
I know you wouldn't want me to
But I never thought that the dictionary in my head
would have that definition erased.
It was stuck in my silly little head
That I could call to you anytime and you'd be here to answer forever
So instead I hold onto my little bit of ignorance
And at night when I go to bed
When everything is dark and as quiet as ever
I whisper: Goodnight Daddy
