All I really need to know about how to live and what to do and how to be, I learned in kindergarten. Wisdom was not at the top of the graduate-school mountain, but there in the sand pile at Sunday School. These are the things I learned. These are the things you already know:
Share everything.
Play Fair.
Don't hit people.
Put things back where you found them.
Clean up your own mess.
Don't take things that aren't yours.
Say you’re sorry when you hurt somebody.
