No, what FF is saying is that the sane homeless are usually homeless because they chose (for example) to pay for drugs instead of the rent.
They have made choices that led directly to their becoming homeless.
Yes, thank you for your response, that's exactly what I was saying.
It's important that you differentiated between sane and those who are bipolar, of which we have many in my area. I work downtown, across the street from the church that has all the programs for them.
