what is a friendship book and book train?

@CTHIETJE Friendship books (also known as "FBs" in their abbreviated form) are small booklets made by stapling paper together, or are sometimes just sheets or strips of paper. They are usually decorated and the person who starts the book writes their name and address as the first person sending the book.

Friendship Books travel all over the world and are passed on from one person to another with letters or in swaps. To keep them moving fast and get them back to their owner sooner try not to keep them longer than two weeks before passing them on again

FRIENDSHIP BOOKS (FB for short) These are small books that are often made by hand. Snail mailers send out these books to each other as a sort of guestbook so their penpals can sign the books and return them. FB's are usually made for someone as a gift to thank them for something.. but often people make them just for fun also. Within a FB you will find commonly used abbreviations - these abbreviations are below. Those people that sign a FB, write in their names and addresses and sometimes their birthday, hobbies and interests. If you receive a FB and don't wish to sign it, you can just write in that you are passing. Friendship books are not just limited to postal swappers - you can also have similar books in email format.

There are unlimited ways to present a Friendship Book... any design and any colors are allowed. When you start swapping you can get FB's in many different shapes and sizes and colors. Sometimes it can take a long time to a FB signed and returned - so remember patience is a virtue. FB Swappers often use stickers, stamps and others prints to decorate a friendship book. Friendship books that are neatly organized and tidy are often referred to as "Nice and Neat" FB's. Other common abbreviations are listed below:
