I often give to beggars. And I would want to give to each one of them, every time.
But as I pass by quite a lot of beggars and homeless people each day (Like 20-something at least), I cannot do that. Not to each one, not every time, not without going into poverty myself.
What I do try to give them, each one I pass, and each time I pass them, is a smile, and my respect.
