Hey! Excuse me i'm a french so if you dont understand...
I have a proposition for help the peoples, easily! !!
It's a thing I want to do! And I think you can do it... I'm a writer, ans the idea is come to me naturally.
1)you take a book note (without notes)
2) at the first page, you write ''this book ils there for you, if you want a confident, write this on the book note''
3) abandon the book note on a place where a person can have this (a park...)
I think it's better if it's in a place where you can sit down!

I propose this because I'm a author so I think the peoples are more happy after write...
I hopes that you understand m'y Dollar's request!!!
