There's a lot to be said for someone who can lose both feet and still be smiling. Especially when those feet are still right in front of him on the pavement. Maybe he's in shock. In fact, given the way he's staring right at us, you almost miss the detail that his friend around the corner is missing a foot, too. In many ways, we suspect that's the whole point.
The person missing both feet is getting showered with money, whereas the one who still has a foot is getting nothing. People have decided that needs of one are greater than the other and acted accordingly. In reality, both people probably need help, and suffering shouldn't be a competition. A person shouldn't have to be in the worst possible state in order to receive human kindness. We all need and deserve that.
