The most pointless conversation you've ever had. English

What's the most pointless(or useless) conversation you've ever had?

My own experience:
It was about 3 or maybe 4 years ago, when I had a "chat" with a businessman from Mainland China in the hope of getting a better understanding of the lives of their people and the way they see the world. Much to my great disappointment, however, it turned out to be a terrible act of self-propaganda... It was meaningless and a disaster for sure.

🙈Too many of them to choose one 😂 …

Besides Self-Propaganda, I've wasted my time writing to online Scammers. I'm guessing that Mainland man was talking about how wonderful it would be for people to see his country.
