Who, what, where, how, and Venn

Do you remember (waking up in Math class and they were discussing) Venn diagrams?  Those overlapping circles that proved that different sets have some things in common?  

Venn diagrams were used by
Algonquin J. Venn
to keep his girlfriends from
finding out about each other
The textbook definition of a Venn diagram says it's "a diagram representing mathematical or logical sets pictorially as circles or closed curves within an enclosing rectangle (the universal set), common elements of the sets being represented by the areas of overlap among the circles."

Think of it this way.  You might like pepperoni pizza, steamed crabs, cheeseburgers and steak for dinner.  (And you would be welcome here any time!)  Your neighbor, a pescatarian, eats fish but no meat, so his meal chart includes steamed crabs, broiled tilapia, cod, and something else, just for the halibut.  

You have something in common, namely, eating crabs, so a Venn diagram would show your two food circles with crabs being the mutual area of overlap.

And, keep eating plenty of pizza, and there will be another area of overlap, I wanna tell ya...

The idea of a Venn diagram came to me the other day when I saw this chart about religion. You see, the more you talk to people about what they believe, the more you find in common. I'm no expert on religion - I may be the only kid who ever had to go to Summer School for Sunday School - but I have spoken to many people about their faiths, and I find that it doesn't matter where or how or when you practice your religion, you want to live your life and not have people get all up in your grille as you do.  

Do unto others as you would have them do unto you.

Simple, and yet...
