Is she homeless?

I don't feel guilty photographing homeless people. They are just like anyone else in Calgary, only they live on the street. They have dreams, troubles, interests, friends, just like anyone else in the world. I wonder if the people I photograph are homeless - like this lady in the center picture. The far bottom guy is someone who was nodding out at Safway during lunch. The security guard kept coming around, almost ready to shoo him away. I think he was high on heroin. The 2 guys below I snapped just below 4th avenue underpass.
