Have you ever met someone who is able to deeply engage in conversation in a wholesome and detailed way?

Yes, I few people.

An old classmate of mine was fascinated about space and space exploration and could go on and on about it. It never was uninteresting to listen to.

Also a friend of mine. He's a pretty smart guy and has opinions on a lot of things. He also knows a lot of things about different topics. We can talk about anything and it will be an engaging conversation. I love that guy.
