It is funny to me how some things affect Leif deeply. Things that I wouldn't normally think about.
A few months ago - about the beginning of summer I think, his class was learning about the planets.
It was a brutal day for Leif when the teacher announced that the 9th "planet", the one called Pluto, was recently declared "not a planet anymore". This bothered Leif a lot and generated lots of follow on questions.
(For the record, I still live in denial and Pluto will always be a planet to me.)
"I don't think Mars is going to be a planet any longer," he said.
Another time he expressed concern that "Earth maybe won't be a planet anymore either like Pluto, and then what happens to us?"
And then they moved on to studying different things... however, the fact that things we once believed and relied upon are subject to change.
"I think that maybe a triceratops is not going to be a dinosaur anymore," he declared one day.
Another day he said that maybe Spanish wouldn't be another language anymore.
Then today he was listing off (correctly) the colors of the rainbow in order of energy. I was highly impressed.
"Where does teal fall?" AB asks him. (I rolled my eyes... why complicate the matter?)
"Dad," Leif says, "teal is not a color anymore."
