This video is labeled as a "social experiment."  Let me say that the people that produced it normally make "prank" videos.  So there's no telling whether or not it's real.  I actually hope it is fake.  In the video you see a boy with a sign that says that he's homeless.  You can see plenty of people walk right by him as he lays on the sidewalk in the 5 degree temperature.  But one person does stop...

 

Do you think that YOU would stop to give this kid a hand?
