There are so little places for teenagers (especially in cities) to actually spend time safely outside of their home without needing to pay some kind of money. Having a safe space for teens to drop not only keeps them safe, but also likely prevents them from committing nonviolent crimes. I’d be very interested in seeing potential statistics comparing cities with well funded teen library drop-in centers and those that don’t and their youth offender reporting statistics.
In my town we had a non-profit literature caffe, it was glorious! In most rooms, we had to keep our voices down, but we could just hang out. Technically, we could order a drink, but I don’t think I ever did. There were hammocks, and books. They sometimes organised activities, like conferences and book presentations. It was housed in an old fancy palace, we felt very fancy going there.
