My father’s grief

He wears a smile on his face
And works almost every day  
He stays up late
Will often go outside to rake
The leaves out of the yard  
I mentioned the missing tombstone  
But all I get is a reply  
That says next time  
My father’s grief
Hides itself  well
I often wish it would come out of its shell
If not sadness then at least shed a tear
So his health I won’t fear
My father’s grief is locked away in a shell
No one knows when it comes out
I wish it was loud
