I thought ... there was something called "weighted random" so I looked it up. Sure enough, such a thing does exist.
http://codetheory.in/weighted-biased-ran...obability/ -- Weighted/Biased Random number generator.
So anyway, there is more than one kind of random.
Also, in scripts, when you write a random number generator, there are many ways to do it. Some of them might possibly try to avoid having the same number come up a lot of times in a row? (Like the gender coin-toss where sometimes you get a cat that makes 10 males and only 2 females ) Some random number generators give a randomer random than others, too ... So that's why I said "more than one kind of random."

Posting your info about the "special size family" "caused" a toy to appear! Hee hee.
Our ability to see patterns (whether they're there or not) is an endearing human trait. Somewhere I read that paranoia was caused by an abundance of pattern-finding ability, and therefore required lots of intelligence to blossom. But then, as they say, "even paranoids have enemies." Some of the patterns are real.
