Yes, or in low-cost housing....
It's very difficult for low-income people who are in those circumstances to go and ask for an attestation. There's a humiliation involved in that. There is often a lack of desire to speak to your landlord to receive an attestation, or to speak to the supervisor of a mission, etc. Sometimes, too, if you're looking at the homeless population, you're on the streets for a couple of weeks, you're in a shelter for a couple of nights, you're crashing there, and you don't know the people running the place. You're not going to ask for an attestation.
As I said, there's a humiliation there. There's an awkwardness and lack of human relationship there that's going to lend itself to that.
