I can relate to this. Few times traveling my with my dad when I was younger, my dad would refuse to give some roadside beggars money. I would be surprised because I know my dad is a cheerful giver, I remember hitting one time to call his attention to see the beggars, he didn't even mind me.
Later he said you can't trust all of them because some are not after just the money, few cases remained unsolved by the police about a victim who gave money to beggars and ran mad or lost a part of the body.
Yup.. I've also heard alot of stories about things like this and trust me when I say it's scary... This is why I think twice before giving money to roadside beggars.
It's really scary bro. Yesterday, a friend and I were on our way to the barber's shop and we met an old woman asking us for money. Sincerely, I really wanted to help even if it was little but I couldn't because of the thigs I've heard.
