I take photos of homeless people now and again, but don't feel very good doing so. I do feel though that the homeless are a large part of an urban experience. Making their presence public is important.
A friend of mine used to work at an architectural office downtown. One of her coworkers would take homeless kids in during the winter, so they could sleep on his floor.
I commend that fellow. If only we could all be generous.
