Amicably

She pulls the knife out of my back

The words I am sorry about that

Sounding almost sincere
Good natured mistake

Lifelong scars are obvious

Well beyond the time line

A blade cuts all the same

The jagged edge does more 

Some mistakes are forever
Soundly sincere contrived

Mocking in amicability
The knife tugs
It cuts all the same
I am sorry almost sincere
