Giving money to a homeless person: stupid?

<p>My history teacher once told me that most of the homeless people that you see on the streets are druggies or alcoholics. The actual “good” homeless people are like … hiding or living in their cars… trying to get their lives back together. I’m pretty sure this doesn’t apply to everyone though.</p>

<p>She also told me this story about her friend giving money to this homeless guy that she always saw at the same spot. Later, she followed him and watched as he drove away in his Mercedez… =|</p>
