Once a month people on your street/block who love books, they gather for an hour.
Each person brings 5 books and make them available for someone to borrow.
Each person can borrow one book. They return it the following month. If nobody else claims it, and if the lender doesn’t withdraw it, they can re-borrow it.
If you can’t make it, you can return the book earlier in person, or ask another neighbour to take it back for you. Either are positives.
A good way to spark conversation and friendship, with little/no downsides.
