I ask because a horrible thing happened recently.
We had a regular beggar (if you'll excuse the term) who sat at the entrance to our work's car park. Karina. She was obviously on drugs. One day she disappeared. About a week later, a small bunch of flowers materialised with a note saying "RIP Mummy". Now a new beggar has moved in.
I regret not having done more. I know that had I given her money, she would have spent it on drugs. But I could have bought her food or hot drinks.
As I said, I regret not having done more.
