PROVERBS WITH THE TITLE : "behaviour"
Do as you would be done by.
Handsome is what handsome does.
It takes all sorts to make a world.
Practice what you preach.
Dogs of the same street bark alike.
What can you expect from a hog but a grunt?
Apple doesn't fall far from the tree
said for :
If all you have is a hammer, everything looks like a nail
There is nowt so queer as folk
You cannot put an old head on young shoulders.
