Thank you @j-vo!
I am not sure if my attitude is positive, like you say, or simply a somewhat detached one. There are all kinds of people on this planet, each with their individual stories, experiences, conclusions, filters. Filters through which they see everything they see, including artworks.
Now, as an artist, imagine giving crucial importance to absolutely each and every opinion that is thrown one's way. That would probably be an expedited way to go crazy. :)
So yes, in that sense, that joke IS priceless...
There's nothing like a humorous anecdote to make a point.
