Take this guy I met in a cafe in Parc Floral in Paris, for instance: around 75 years old, he spent at least half an hour sitting in that position talking to another oldie (who looked absolutely like a standard normal oldie).
He went on ranting about the conformism of society for the whole time.
"Fait chier cette connerie de la pensee unique !!!... merde. societe de merde. la pensee unique, et merde"
Then his wife came, sat in front of him and said:
"T'es vraiment un sale casse-couilles."
Voila'.
