Many years ago I once tried to share a History channel documentary on the JFK assassination with a friend. They watched up until the first part, the documentary dramaticized the assassination and talked about how the shot seemed impossible based off the shape of the car.

See I had already watched this documentary in full, and knew that this was just a cliffhanger for the second part that explained the car was modified, making the seemingly impossible shot very possible. Yet, my friend said "See? That's enough evidence." and walked away.

I asked, "don't you want to hear the rest?" the response: "nope."

Your comment reminds me of this experience
