It's a two-dimensional analogy of general relativity for people who won't get it no matter how much you dumb it down.

 

 

 

 

 

"I am a wondrous creature, a joy to women,
a help to neighbours; I harm none
of the city-dwellers, except for my killer.
My base is steep and high, I stand in a bed,
shaggy somewhere beneath. Sometimes ventures
the very beautiful daughter of a churl,
a maid proud in mind, so that she grabs hold of me,
rubs me to redness, ravages my head,
forces me into a fastness. Immediately she feels
my meeting, the one who confines me,
the curly-locked woman. Wet will be that eye."
