Temperament
Elicitor of emotions,
Diabolical channel
Of reactions,
Discombobulating
A gentle state,
Wants be my fate…
Temperament
Destabilizing
Congruence,
Imposing burdens
Of wrathful kind…
Temperament
Blackened by stage
Of paroxysmal rage,
Like an enervate pawn
I search to stay the way,
Of temperamental sway!

Temperament, from whence it came no one knows. More food for this with this from you. Have a great weekend, ya’ll.
You are right about nobody seems to know where it comes from for sure. When I was putting that piece together, I was curious about its influence on humans as well as animals, and in spite of the many scientific researches and opinions, going back a number of years, all seem to end with, in so many words, not too sure as in nothing conclusive. You confirm what I found.. Only you my learned friend comes thru. Thank you for that, and a great weekend to you and yours too. Jean-Jacques
