"it is very hard to turn down someone genuinely in need, especially, as Blast mentioned, the very young and the very old."

Oh, I fully agree. But the very young and the very old are usually accompanied by those who fall in between, the ones who should have known better and done better.

My major discomfort zone: how many of the hordes am I capable of helping? Where do you cross the line from enough to too many? Can you even tell where the line is, until its too late?
