I’m pretty sure this is what a telepathic conversation looks like.
i could literally have gone my entire life without watching sherlock and would have been happy and free without a care in the world but no we have this

Up until that point, John almost seems in denial about what is obviously about to happen. But he clearly knows- the first thing out of his mouth when he sees where Sherlock is standing is “oh, God.” Not once during their conversation do they bring up the fact that Sherlock is standing on a ledge or that John is trying to talk him down. Even when Sherlock says, “It’s what people do, don’t they? Leave a note.” John naively asks, “Leave a note when?” when he clearly knows the answer to that. After all, their first case together revolved around a woman committing suicide and leaving a note. But John seems unable to accept that his friend is about to kill himself. When Sherlock says “Goodbye, John”, he replies with a denial. Because he refuses to accept that this really is ‘goodbye’.
