Why I never replied

Its been a while I have known her
Doesnt feel like that
She treats me like a stranger
Never has been a day that past
And now i dont remember
when i spoke to her last
And I thought i would write a song
And things will mend
Matters will move along
She never cared so I stopped
A train to a destination
Away from her I hopped
Time went by and one day came
Are you alright?
Where is the song you were gonna frame
I smiled politely and replied
I did write
But there was no number
So I never replied
