Ok if you’ve never heard of it, I sure didn't, stupid me, it goes like this: You make a little book with a few pages in it, write whatever you want about yourself and send it to a penpal, for instance. Then he or she will send it someone else and it goes on, traveling the world. But of course you need to have your address there to make sure the book returns to you at the end of the whole trip. Yay! I should go make one soon! Hmm…who should I send it to? I sure hope it leaves the country and comes back to me one day.
