“She came right down in my face,” Sturtz said. “I was taken aback.”

135. Action /reaction

cause and effect.

No doubt Sturtz thought out all probable scenarios leading to an inevitable exit via escort. All eyes on the heckler protester what have you.
But having the table reversed did not prefigure.
kind of like a surprise counter attack initiated to the order of the immediate, the thing that cannot possibly happen.

Disruptor's disrupt in public places -they go off on crazy rants and people as a rule just watch. Eventually someone from the establishment will deal with it. People just watch and wait for it to be dealt with somehow by somebody.

Make no mistake the first ladies time is valuable and the heckler was wasting valuable time.
The point to it was staying involved -get involved ,remain involved. Do something other than wait and watch.

When they insisted that the first lady stay and continue-thats getting involved actively.They took back what theirs in time.

Cause and effect.

Can't' confront all those hecklers that way- and yea,that was good !
The table was turned perfectly on the heckler,protester what have you. and the point was put across perfectly-get involved -stay involved -be more than just a spectator.
