The odds and evens bit is what got me. I have an obsession with numbers. Certain numbers must be even and others odd.

Examples:

Evens: The radio and TV volumes must be even. (I hate that FM stations are odd.)

Odds: I count the letters of every sign I see and if they aren’t odd, I count the spaces. If the total is still not odd, I count a line or graphic to make it odd, or I’ll count only the lower case letters. It’s always possible to make it odd, just requires some serious imagination.

Thanks for the article!
