Pick up that Crisp Packet !
"Pick up that Crisp Packet!" I read "Pick up that Crisp Packet !" This book told me the importance of picking up small trash. If no one thinks one crisp packet does not matter and pick up it, the place will be gotten dirty gradually. Because other people begin to throw away their trash thinking that they are allowed to throw away in the place. I understood it is important that everyone are conscious cleanliness.
