O'Felix, The Number 2, and Pluto (or How the IAU Broke a Young Boy's Heart)

Felix has some likes. He likes the letter O, he likes it so much he insists his name begin with it when we write it out. I'm not sure where he developed his affection for the letter O, but I can understand it- it's a nice looking letter.
Tru likes the number 2. I think 2 gained a place in his heart when he was two. Even though he is three, it seems he remembers two very fondly and commemorates that age by collecting items with 2 on them. Playing games that involve numbered cards can become difficult as the only cards he is interested in are the cards with a 2 on them. Sometimes, if he sees me writing, he'll ask that I write a 2 on a sheet and give it to him. Renae writes her 2's with a loop. Oh no. No, no, no, that is all wrong, write it again mom.
And then there's Pluto.

Felix had shown some interest in the stars so a while back we borrowed astronomy books for kids from the library. He really took to them and he learned to identify several of the planets- including Pluto, his favorite (I think it may have become his favorite because of O). As the book was a little older it listed Pluto as a planet. I showed him a newer book where Pluto was excluded. He asked where Pluto was and I told him that on August 24th, 2006, the International Astronomical Union reclassified Pluto and that it was no longer considered a planet. Well, maybe just the part about Pluto no longer being considered a planet.
DENIAL
"No dad, it's still a planet" he says. I explained to him that some scientists had decided it wasn't after the first book was written.
BARGAINING
He gingerly puts his hand on my face to direct my gaze into his soft eyes as he sweetly says "But it still could be, we could read this book". I explain that that book is older and that information has been superseded.
ANGER
"No dad, it's a planet!" he commands. I try to move us along and ask if he wants to keep reading.
DEPRESSION
He does want to keep reading, but he doesn't really care which book, and he seems kind of bummed out.
And that is where it was for several weeks. Well we got past it. I still read him astronomy books, but ones that excluded Pluto as a planet. Then a couple of days ago, Renae and Felix find a book specifically about Pluto at the library, and last night I read it to him. The first sentence starts "Pluto is a dwarf planet..." and Felix interrupts "Pluto is not a planet". I tell him that he is correct but "dwarf planet" is a different classification than planet. He says "okay, but it's not a planet". ACCEPTANCE
