9, mabye 10

I remember being a kid. Things were different then. Girls and boys still played separately on the playground until high school. We still had playgrounds at schools. Playgrounds still had playground equipment.
There were a lot of things in outerspace too. I don't exactly remember when the earth was the center of the universe (a bit before my time), but I remember that the sun was the center of our solar system. And then the planets. Oh .. the planets. Nine of them, and then later in high school, some crazy scientist thought he might have found another one, out near Pluto. Imagine that, 10 planets. They might even give it a cool name like 'Uranus.' Or something stupid like O89B673. Astrologers weren't always that boring.
Kids these days. 8 planets. Its almost too easy. What is next? Will Jupiter stop being a planet because it is too big? (DRUM ROLL PLEASE) "Ladies and Gentleman, I am pleased to announce that you are now living in a twin sun solar system, with 7 planets. Please pack your bags in anticipation of our sun becoming a red dwarf. We will be leaving for Alpha Centauri in 2 Billion 700 Million years."
Now I don't meant to be nostalgic. Nostalgia just isn't what it used to be. But then again, neither is our solar system.
