I've made five posts so far today, five is a nice odd number.
But one of them was private.
So to all the others of both friends-only and public varieties, I must add another to make it up to a real five.
Odd numbers are attractive because you can point to a stable centre. In art, in most things, they are better and I prefer them.
In maths, even numbers are nicer. But primes are so solid, stubborn, try to factorise me if you dare!! I like it when the number 21 crops up, because it is seven times three, two primes, two nice odd numbers, seven being the superior. Besides, 21's digits add to three again. Seven and the two threes comes to thirteen, and that's nice too, the prime that somehow sticks out lucky or not.
