I was a bit upset but I tried to be nice about it and ask him to impress upon his grandson how completely unsafe it was for him to do that.
The grandfather's response was exactly what this article references;
"If those other warbird pilots can do what they want why can't my grandson?" Then he called me a few expletives and told me where I could stick my safety concerns.
You might get better results if you use the OTMOC (One True Method of Communication): "When you do [blank] it makes me feel [blank]". When you use the traditional "You' method, e.g. "You are doing something extremely unsafe", 90% of the time you'll get the answer you got, and the behavior will not change. Instead, try something like, "When you do a fast low pass when I'm at the flight line, it makes it very hard for me to concentrate on my flying." Most people will be more receptive to changing their behavior if you don't frame it as a lack of character, or education, or any deficiency on their part.
