When this father in China saw his distraught daughter sitting on the ledge outside their window, he knew the situation was dire. Looking up from the sidewalk, he figured he didn't have time to run up the stairs to their third-floor apartment. It might actually scare her into jumping.
Instead, he did what most fathers or Spider-Man fans would do, and started scaling the side of the building. When he finally reaches his daughter, he seems more angry than anything, but having to climb a building and risk falling to your own death can probably foul a person's mood. Overall, I bet he's relieved. We sure are.
