“All I Need to Know I Learnt in Kindergarten” By Robert Fulg

Speaking of manners, here is a few sentences from the book, All I Really Need To Know I Learned In Kindergarten"  by Robert Fulghum

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. Wash your hands before you eat.

Flush.

Since we are adults, I also add : choose kindness over righteousness.

Patience, and more patience.
