What's the difference between a saying and a proverb?

Or, for that matter, between tradition and folklore?

Of this new month, March, it's been said that if it comes in like a lion, it will go out like a lamb, a saying that has a number of possible origins (all of which may well be a kind of folklore all their own). 

And I suppose the converse might be considered true when it comes in the way this one has -- sweet and mild as our city-bred visions of what a lamb must be like (even though wobbly little lambs can be pretty feisty, ready to nip at fingers, hoping they might work the same way teats do).

So, does that mean our Easter weekend will be wild and blustery? Who knows. We've got the rest of the month to find out.
