Pluto

So I'm in a class today and we're debating about Pluto (we're learning about the solar system) being a planet. I think Pluto should be a real Planet. We're getting too technical here with all these categories. (reaching mental campacity!) But thats not the only reason. My teacher said that for a somthing to be a planet it must: 1. orbit the sun - 2. be not too big or too small- 3. Dominate its own orbit. Drawrf planets meet 1 and 2, but not 3. And since Pluto is a drawrf planet, it doesn't dominate its own orbit (which is true) but I think it's a really stupid reason to not be a planet. I bet Pluto's really depressed right now (Poor Pluto!)
