I think people who beg on the street doesn`t do that for "fun". They have a right to be there, and a right to ask for help- I give them something when I pass by. But it saddens me to see them, because it shouldn`t be like that.
Even if people are addicts, wether they use drugs or are alcoholics, they have the same value as human beings, and should be treated decent. Who knows what their story is, and what lead them to where they are now?
Have you ever seen someone being ill, and nobody helped them?
