A post just reminded me of a prank I watched on YouTube, where a homeless person searching the garbage for something to eat asks for change from passing people, who didn't give him anything, but then the same people few meters away asked for change by a beautiful lady for change to put in the parking meter because she didn't have change with a car parking near
the meter, and they quickly gave change while smiling and trying to talk to the lady (apparently, they were men), and then the homeless man would appear from nowhere and point to them and laugh!! It might be funny (it wasn't for me. For me it was more of a social experiment), but the moral of the story is very strong. People don't help those in need, but those who deserve help according them. Apparently the homeless man didn't have anything to offer back to these men. I would say everything in life is very similar to this scenario. Everything is about self-interest. For everything people do there is a question asked: "what's in it for me?"
