For anyone who's played Zelda, Breath of the Wild, there is a character who patrols a bridge to keep it safe from monster. If you jump on the edge of the bridge, he will talk you down and then offer to continue conversation.
I thought I read it was based on a japanese person, but it may have been based on an american cop who patrolled a bridge in san francisco.
Either way, it reminded me of this story. At the point at which you find this bridge character you are likely feeling quite down about the game world, and isolated. So it's a more poignant scene than I can describe in text.
