Is is that you like 30 and 10 because they are nice 'complete' numbers? Yes, I can dig that

When I was a kid I had a thing about even numbers, odd numbers made me uncomfortable. I could never understand why clocks had 12 numbers, even though 12 is even, I always thought there should have been ten because ten is more, well, just feels right .

I have to agree... 10 is a much better choice. Plus with the metric system having a base of 10 it just makes sense. But there's the world for you.
