A Few Bad Apples (and Rampantly Unhygienic Ones, Too)
Keep in mind that the homeless in the 1930s were sort of quaint and charming (and mostly in black and white or sepia toned). They wore suits and had dreams of rabbit farms and getting back on their feet. If you had a job, who would you give a buck to: Burl Ives or Ratso Rizzo from A Midnight Cowboy?
...that knowing when to let go of people who have already let go of you is good. Actually letting them go and moving on is better.
