The Most Basic Rules

Do unto others only what you would have done to you.
 
from Ann Landers:

1. If you open it, close it. 
2. If you turn it on, turn it off. 
3. If you unlock it, lock it up. 
4. If you break it, admit it. 
5. If you can’t fix it, call someone who can. 
6. If you borrow it, return it. 
7. If you value it, take care of it. 
8. If you make a mess, clean it up. 
9. If you move it, put it back.
10. If it belongs to someone else, get permission to use it. 
11. If you don’t know how to operate it, leave it alone. 
12. If it’s none of your business, don’t ask questions. 

Because someone does something wrong, is no excuse for you to do the same. 

Be your best, even if no one else is.

Try to live your life, so that when you get old you do not regret your past actions.
