There are some things parents are better off not knowing.
I have for the past three decades maintained a strict police of complete parental ignorance when it comes to my sex life. My mom and dad may have inferred certain things about me, based upon the existence of a grandchild, but I have yet to cop to anything specific. They can't prove that my son is not the product of a home chemistry kit and a turkey baster, and I'm content with that level of ambiguity.
So, this guy who let his mother read the explicit and unwholesome messages sent to him on Grindr* is like some strange alien species to me. I'm intrigued by his actions, but I cannot in any way understand his motivations.
* I want to say that Grindr is like Tinder for gay people, but, in reality, Tinder is Grindr for straight people.
