A friend with the name of Dimitar wrote a poem.
The last stanza reads like this:
I’ll go no more a roving o’,
With you no more I’ll range.
Ill clench my teeth, I’ll bite my lip,
For you’re the same but I have changed.
So this cartoon is dedicated to the last stanza and the poem can be found in full here: http://thesaker.is/moveable-feast-cafe-2021-08-13/#comment-964011
