To me, it's not about 'bossy'. It is, however, about know-it-alls or in the case I'm referring to 'think-it-alls' and brother, have you got a dime. lol

This hit's home truly because it dovetails into the hypocritical as well i.e. people who are staunch advocates for people being verbally gobsmacked, but are not above it themselves when (in their minds) confronted with 'inferiors' .....

It can be frustrating but I don't dwell, I simply rinse...and I would advise same for you, with one caveat: If they are an insistent blow hard and it may cause you injury cause others believe the load of tripe...step up or step back but never follow along.

Other than that, you seem to have the wisest angle on a most angular situation...so worry not. There are 'blow hards' everywhere. Recognition is key to dismissal. :P
