There’s a homeless shelter 2 blocks away from me, and I’m perfectly fine with it. The residents are great people as far as I can tell; I smile and wave when I see them, and I don’t begrudge the occasional panhandler or guy mumbling to himself.
I mention all that to be very clear about what I mean when I say, I wouldn’t agree to live near a San Francisco homeless shelter either. I just can’t tolerate people screaming at me all the time or scattering used needles on the sidewalk outside, and definitely couldn’t ask friends or family to tolerate it.
