Did you hear that Pluto is back to being a full planet again? :D
The promblem with the dwarf planet kerfuffle was that people were imagining that "planet" was a term with a specific scientific definition… or at least they tried to give it one, but that never really worked, because there IS no such thing as a "planet" per se, just things we choose to call planets. It's a cultural definition.
Then there were the people that said all the other round objects out in the far asteroid belt should be full planets as well then, but that doesn't follow either: we call Europe and Asia "continents" and we have that on maps, geography books etc… even though there's no seperation between them appart from national borders and history, and even that is blurred.
If we choose to name Pluto a planet and not the other objects, so what?
That's great news! The Scarf household were inexplicably downhearted when Pluto was downgraded. My daughter couldn't stand the idea of Pluto being bullied by all those gas giants:
"Nyah, look at you - yer just a cloudless lump o' rock - sod off to the Kuiper Belt and don't come back!"
Here's to plucky little Pluto and his girlfriend Charon: don't lat the gastards grind you down.
