I was going to make the same comment. What's lost in the distortion of image for propaganda, and even in the discussion of what really happened at Tiananmen is this:

It's an incredibly human moment. Amidst days of protests, lynchings, shootings, beatings, fire and violence two people had a conversation. We don't know what was said or who they were. They could have screamed insults at each other, pleaded to see each other's point of view, or just talked about crazy this had all gotten. But they had a conversation, as two people and the result was that everyone lived.
