Earlier generations were much more disciplined and tidiness was one of the things that meant so much. Our grandmother's rule was -A place for everything and everything in its place.

Some old ideas still apply in todays world. How about this notice....?

 If you open it, close it.
If you turn it on, turn it off.
 If you unlock it, lock it up.
If you break it, admit it.
 If you borrow it, return it.
If you move it, put it back.
 If you make a mess, clean it up.
