Do you have a mansplainer in your entourage?

One of my friends is one, he knows all he has to explain everything to everyone that he has such stupid opinions like texting has ruined human relationships. But I tell him that people are just used to texting. It’s just a new way of communicating. A lot of people don’t want to talk on the phone any more.
But he tells me I’m wrong in so many ways he thinks he’s a visionary🙄
