I just read on Facebook about Clara's outburst over being told, by her mom, that she couldn't have any gum. In Kelsey's words: "She folded her arms and told me, 'I'm very mad at you. I'm mad at you all the way to space. Space is a very long way from here. You have to take a rocketship to get there. I am zero three thirty mad.'"
I commented on Kelsey's FB post that I'm pretty sure I've been "zero three thirty mad" at a few people in my life, but just didn't know what to call it. Now I do! Had to learn it from a 5-year-old.
