People talking about libraries, and I'd like to add from long-term experience that if you're homeless, those places are vital. Reading the newspaper while sitting on, y'know, a *chair*, hopefully a drinking fountain (No dehydration? Fancy) reading some books, not being too cold or too hot, lovely.
Oh, and you can sort out official stuff, which is handy when you ain't got an address. There was even a lady at one who liked to share food around. Like, you didn't eat it inside, obviously, but food? Nice.
Hell, just about the only things they didn't have were a place to wash or sleep, but you could learn stuff, rest a little, get out of the weather, not be on your guard all the time, (and can't get arrested, cause you're not 'loitering' in a library) and, here's the good part:
You could send your mind somewhere else. Like, without chemicals. You pick up a book and you just escape. That's priceless if you're homeless.
Which is the perfect price, cause you ain't got money.
A heart. A soul. A mind. That's what a library is. And bless em for existing.
Gonna stop there, cause I'm getting all teary and shit.
