A few weeks ago, I met a guy who asked me for some change. I respect men who muster the courage to ask for help, so I gave him what I had on me. Today, I saw the same guy in the same spot. He approached me, called me his friend, and asked for change again. At that moment, I felt like if I continued to give, this could turn into a pattern. So this time, I politely refused. He became upset and walked away. What would you have done?
