Just like in the real world. There are two types of beggars. They both want your money, but one actually looks at you and tries to connect with you, and the second one it´s like a panhandling robot.
The first type gets to me, and I´ve been known to even buy them food like hamburgers and stuff on occasions, and I´ve even stayed half an hour chatting them up every now and then, since like every human being down on the weather, they need company too. Usually they are just normal people who had troubles they couldn´t recover from.
The second type had lost touch with their humanity, and yours too, and are out there just to scam you.
It´s quite easy to distinguish between both of them once you get used to it...
I missed this whole post of yours. I've met some interesting people with stories to share. A homeless gentleman in Kingston Jamaica by the name of Donovan gave me some very helpful advice about love once.
