I know why
Yoda sighs… — The helpless, exasperated, ejaculation uttered when someone who is suppose to be watching your back completely misses the
mark.
Your mission partner only has one well articulated and necessary
job necessary for the successful completion of “THE PLAN” and they absolutely blow it.
The origin of this expression is the scene in the movie: The Empire Strikes Back when the Jedi Master
Yoda deeply sighs after Luke Skywalker fails his test inside of the Dark Side tree.
Luke had one job…ONE JOB!!!!!!!
And he blew it; HE BLEW IT!!!!!!!!!!
And Yoda sighed!!!!!
