I couldn’t agree more, on all counts.
Next time you travel, try taking a book or two that you got at a secondhand bookstore and leave it behind somewhere for someone else to find, whether you liked it or not. You never know what someone else might think of it.
I discovered so many great vintagey children’s books on my travels when I was a kid, and M. and I always try to duck into at least one used book store on our trips. Have you ever found a gem (or a stinker!) while on holiday?
