That would be a dream, and it's possible actually.. but unfortunately I don't think most homeless people have that long term thinking since they often need money on a daily basis.
This guy seems different though. He uses the bins and cleans up after himself so well. He looks like a really decent guy that just somehow ended up on the streets. One time when I offered to buy him lunch, he picked the money saving option (meal deal) and no extra stuff 😲
