I really like this: http://www.mymodernmet.com/profiles/blogs/birmingham-spiderman-feeds-homeless
I like it because the idea of Spiderman going around helping people is perfectly normal. I think sometimes when a “regular” person approaches a homeless one, it can seem a little awkward or uncomfortable– an interaction between people who aren’t equal, or between people who don’t have a clear relationship. Generally the understood relationship is that homeless people are invisible to regular people.
I imagine a homeless person would find it easier to accept help from a Spiderman than a regular stranger– unless maybe they’ve been pranked or punked before. Or maybe I’m wrong about that– I wouldn’t know, because I’ve never been homeless. But it’s interesting just to think about how we perceive the whole act differently once the costume is involved.
