There's nothing wrong with not arguing with a guy you might be stuck with on a 4-day trip simply to save pride. Sometimes a quiet cockpit is best purely for sanity.

I simply smile when some jackass talks or looks down at me when I fly a little 150 at the FBO for fun and they get out of their Baron, King Air or helicopter, full well knowing that I fly something bigger, better, and all over the world, seeing things they only wish they could. What they don't know doesn't hurt them, and they still get to go home and think they're cool.

Long story short - chill. Step back, let people talk. Guaranteed, you aren't the only one who thinks someone is a blowhard.
