A frame on the wall

Don’t you leave me
I know I caused pain
But a little now
Is a shot
Against a rend heart
In time to come

We be the glue
That holds the poster on the wall
Two of a kind
Been placed and replaced

The glue has lost its use
It cannot hold us together
A little of the wall
Has been left behind on us

Even the newest house
And the shiniest paint
Cannot anymore charm us
Sooner than said
The grip will be lost
And hurt ourselves we will
By landing on the floor
