I agree, Barb. Sometimes the get-outta-my-face and off-my-back approach does wonders to get an A to sit down and shut up - possibly from the shock of hearing the reaction! But, hey, if it works ...
An A with tons of recovery advised me to try it when I was whining about AH's latest shenanigans to drive me batty. He backed down big time when I went toe-to-toe and made it clear I wanted him to shut his big bazoo.
