I agree with your wife, I have great friends from the plastic and performing arts, gatherings with them are pleasant, and friendship with them is a manifestation of the nobility that is nested in each of them. Very different from what is nested in the business world dawned by hatreds, rivalry, competition, envy and disqualifications.
There is still some competition in them, but it is still in a different way, less petty or something.
It is possible that the competence, the aesthetic language is very particular and subjective to consolidate the creation, among them.
