Hmm. I don’t know. Could I be considered an authority on anything, though I dare say I am more knowledgeable than most of my circle of friends at bathroom design, and within the people I know, I am probably the biggest Nintendo fan. I could talk your ear off about Formula 1, or Disney stuff, and Star Trek is a topic I could waffle about for hours, but does that make me an authority? Should other people regard my opinions and views with reverence? No. I speak for myself and only myself. I may, depending on the subject, project confidence in my opinions, but I don’t pretend my opinions are worth more than anyone else’s (unlike some people I know). I am in no doubt that there are people out there with a lot more knowledge about bathrooms, Nintendo, sci-fi and pretty much anything I’m interested in.
On the other hand, I guess to customers asking about bathroom stuff, I am an authority, relative to them. It’s all relative, I suppose.
