Every homeless man/woman that approaches you is you. Your first thought is to recoil, pay them no mind, walk on by.
Protect your turf. You work hard every day and here is this slacker asking you to part with your hard earned dollar. He will use it for a quick fix. This person is not you. Why do you quicken your step? Your ego mind says this person is a threat. The ego mind says this is not you.
Next time this happens, stop, listen and be present. You may be surprised that this human being wants to talk for a moment and be recognized as another human being. You may not have to part with any money and may learn something about your own true nature.
