Visual exchange that provides satisfaction perhaps (2,3,3,2,3)
I believe the answer is:
an eye for an eye
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for an eye for an eye that I've seen before include "Retribution" , "Retaliation principle (2,3,3,2,3)" , "The law of retaliation (2,3,3,2,3)" , "an exchange of views?" , "Retaliation in kind" .)
